Auto-Turning ON the CL865 To Auto-turn on the CL865, the power supply must be applied on the power pins VBATT and VBATT_PA, after 5000 m-seconds, the V_AUX / PWRMON pin will be at the high logic level and the module can be considered fully operating. The following flow chart shows the proper turn on procedure:
Modem ON Proc. PWR supply = ON?
Y PWMON = ON?
N Delay 1s - 5s for Low Voltage Operating PWMON = ON?
N Y N Y Delay 1s Delay 300mS Enter AT<CR>
AT answer in 1second ?

The power supply must be applied either at the same time on pins VBATT and VBATT_PA, or first applied on VBATT_PA and then on VBATT. The opposite sequence shall be avoided. The reverse procedure applies for powering down the module: first disconnect VBATT, then VBATT_PA, or both at once. NOTE:
In order to prevent a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the CL865 when the module is powered OFF or during an ON/OFF transition. A flow chart showing the AT commands managing procedure is displayed below:

General turn OFF Processor turn OFF General turn OFF disconnect the power supply from the both power pins VBATT and VBATT_PA at the same time. In this case all parts of the module are in OFF condition, no power consumption is present. Processor turn OFF disconnect the power supply only from the power pin VBATT, the power pin VBATT_PA can be connected to power supply, in this case a low, about 30uA, power consumption is present Before either of both OFF procedures is applied, the AT#SYSHALT AT command must be sent (see AT Commands Reference Guide), after the OK response message, wait for 10 seconds, then the module can be consider fully not operating and at this moment is possible disconnect the Power Supply.

Modem OFF Proc. AT#SYSHALT 10s timeout Disconnect PWR supply Delay 1.5s Modem ON Proc. WARNING:
POWERMON can be used to monitor only the power on but it cannot be used to monitor the power off because it remains high. NOTE:
In order to prevent a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the CL865 when the module is powered off or during an ON/OFF transition.

Hardware Unconditional Shutdown CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 2014-03-07 The Unconditional shutdown of the module could be activated using the RESET* line (pad 47). WARNING:
The hardware unconditional shutdown must NOT be used during normal operation of the device since it does not detach the device from the network. It shall be used as an emergency exit procedure. To unconditionally shutdown the CL865, the pad RESET* must be tied low for at least 800 milliseconds and then released. NOTE:
Do not use any pull up resistor on the RESET* line nor any totem pole digital output. It is pulled up internally to VBATT with 57k. Using an external pull up resistor may bring latch up problems on the CL865 power regulator and improper functioning of the module. The line RESET* must be connected only in open collector configuration. The RESET* will generate an unconditional shutdown of the module without an automatic restart. The module will shutdown but will NOT perform the detach from the cellular network. To proper power on again the module please refer to 5.1 Auto-Turning ON the CL865. TIP:

Power Supply The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performance, hence read the requirements carefully and the guidelines that will follow for a proper design. 6.1. Power Supply Requirements The external power supply must be connected to VBATT & VBATT_PA signals and must fulfill the following requirements:
POWER SUPPLY Nominal Supply Voltage Normal Operating Voltage Range Extended Operating Voltage Range 3.8 V 3.4 V ~ 4.2 V 3.4 V ~ 4.5 V NOTE:
The Operating Voltage Range MUST never be exceeded. Special care must be taken when designing the applications power supply section to avoid having an excessive voltage drop. If the voltage drop is exceeding the limits it could cause a Power Off of the module. Behavior in the extended operating voltage range might deviate from 3GPP2 specification.

General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps:
the electrical design the thermal design the PCB layout 6.3.1. Electrical Design Guidelines The electrical design of the power supply depends strongly on the power source from which this power is drained. We will distinguish them into three categories:
+5V input (typically PC internal regulator output)
+12V input (typically automotive) Battery 6.3.2.
+ 5V Input Source Power Supply Design Guidelines The desired output for the power supply is 3.8V, hence there is not a big difference between the input source and the desired output so a linear regulator can be used. A switching power supply will not be suitable because of the low drop-out requirements. When using a linear regulator, a proper heat sink must be provided in order to dissipate the power generated. A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks close to the CL865. A 100F tantalum capacitor is usually suited. Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. A protection diode must be inserted close to the power input in order to save the CL865 from power polarity inversion.

6.3.3.
+ 12V Input Source Power Supply Design Guidelines The desired output for the power supply is 3.8V, hence due to the big difference between the input source and the desired output, a linear regulator is not suitable and must not be used. A switching power supply would be preferable because of its better efficiency, especially with the 1A peak current load represented by CL865. When using a switching regulator, a 500 kHz or more switching frequency regulator is preferable because of its smaller inductor size and its faster transient response. This allows the regulator to respond quickly to the current peaks absorption. In any case, the frequency and switching design selection is related to the application to be developed due to the fact the switching frequency could also generate EMC interferences. For car PB battery the input voltage can rise up to 15.8V and this must be kept in mind when choosing components: all components in the power supply must withstand this voltage. A bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks. A 100F tantalum capacitor is usually suited for this. Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. For car applications a spike protection diode must be inserted close to the power input in order to clean the supply from spikes. A protection diode must be inserted close to the power input in order to save the CL865 from power polarity inversion. This can be the same diode as for spike protection.

6.3.4. Battery Source Power Supply Design Guidelines The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V. A single 3.7V lithium-ion cell battery type is ideal to supply power to the Telit CL865 module. WARNING:
The three battery cells (Ni/Cd or Ni/MH 3.6V nom. battery types or 4V PB types) MUST NOT be used directly because their maximum voltage can rise over the absolute maximum voltage for the CL865 and cause damage. USE only Li-Ion battery types. A bypass low (usually a 100uF tantalum) ESR capacitor with adequate capacity must be provided in order to cut the current absorption peaks. Make sure the low ESR capacitor (usually a tantalum) is rated at least 10V. A protection diode must be inserted close to the power input in order to protect the CL865 module from power polarity inversions when connecting the battery. The battery capacity must be at least 500mAh in order to withstand the current peaks of 1A. The suggested battery capacity is from 500mAh to 1000mAh.

Thermal Design Guidelines The thermal design for the power supply heat sink must be done with the following specifications:
Average current consumption during CDMA 1x @PWR level max : 620mA NOTE:
The average consumption during transmissions depends on the power level at which the device is requested to transmit via the network. The average current consumption hence varies significantly. Considering the very low current during idle, especially if the Power Saving function is enabled, it is possible to consider from the thermal point of view that the device absorbs current significantly only during calls. If we assume that the device stays in transmission for short periods of time (a few minutes) and then remains for quite a long time in idle (one hour), then the power supply always has time to cool down between the calls and the heat sink could be smaller than the calculated for 620mA maximum RMS current. There could even be a simple chip package (no heat sink). Moreover in average network conditions the device is requested to transmit at a lower power level than the maximum and hence the current consumption will be less than 620 mA (usually around 300 mA). For these reasons the thermal design is rarely a concern and the simple ground plane where the power supply chip is placed can be enough to ensure a good thermal condition and avoid overheating. The heat generated by the CL865 must be taken into consideration during transmission at 24.5dBm max during calls. This generated heat will be mostly conducted to the ground plane under the CL865. The application must be able to dissipate heat. In the CDMA 1x mode, since CL865 emits RF signals continuously during transmission, special attention must be paid to how to dissipate the heat generated. The current consumption will be up to about 620mA in CDMA 1x continuously at the maximum TX output power (24.5dBm). Thus, you must arrange the area on the application PCB must be as large as possible under CL865. The CL865 must be mounted on the large ground area of the application board and make many ground vias to dissipate the heat.

Power Supply PCB layout Guidelines As seen in the electrical design guidelines, the power supply must have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct operation of the circuitry. A misplaced component can be useless or can even decrease the power supply performance. The bypass low ESR capacitor must be placed close to the Telit CL865 power input pads, or if the power supply is a switching type, the capacitor can be placed close to the inductor to cut the ripple if the PCB trace from the capacitor to CL865 is wide enough to ensure a drop-less connection even during the 1A current peaks. The protection diode must be placed close to the input connector where the power source is drained. The PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occur when the 1A current peaks are absorbed. While a voltage drop of hundreds of mV may be acceptable from the power loss point of view, the same voltage drop may not be acceptable from the noise point of view. If the application does not have an audio interface but only uses the data feature of the Telit CL865, then this noise is not as disruptive and the power supply layout design can be more forgiving. The PCB traces to CL865 and the Bypass capacitor must be wide enough to ensure no significant voltage drops occur when the 1A current peaks are absorbed. This is a must for the same above-mentioned reasons. Try to keep this trace as short as possible. The PCB traces connecting the switching output to the inductor and the switching diode must be kept as short as possible by placing the inductor and the diode very close to the power switching IC (only for switching power supply). This is done in order to reduce the radiated field (noise) at the switching frequency (usually 100-500 kHz). The use of a good common ground plane is suggested. The placement of the power supply on the board must be done in a way to guarantee that the high current return paths in the ground plane are not overlapped with any noise sensitive circuitry such as the microphone amplifier/buffer or earphone amplifier. The power supply input cables must be kept separate from noise sensitive lines such as microphone/earphone cables.

Antenna The antenna connection and board layout design are the most important parts in the full product design and they strongly reflect on the products overall performance. Read carefully and follow the requirements and the guidelines for a proper design. 7.1. CDMA Antenna Requirements The antenna for a Telit CL865 device must fulfill the following requirements:
Frequency range Bandwidth Gain Impedance Input power VSWR absolute max VSWR recommended CL865 Specifications Depending on the frequency band(s) provided by the network operator, the customer must use the most suitable antenna for that/those band(s) 70 MHz in CDMA BC0 53 MHz in CDMA BC10 (subclass 2,3) 140 MHz in CDMA BC1 Gain < 5.12dBi in CDMA BC0 Gain < 5.12dBi in CDMA BC10 (subclass 2,3) Gain < 6.12dBi in CDMA BC1 50 Ohm
> 24.5dBm Average Power in CDMA 5:1 (Limit to avoid permanent damage) 2:1 (Limit to fulfill all regulatory requirement) When using the Telit CL865, since theres no antenna connector on the module, the antenna must be connected to the CL865 antenna pad (pin 34) by means of a transmission line implemented in the PCB. In the case that the antenna is not directly connected at the antenna pad of the CL865, then a PCB line is required. This transmission line shall fulfill the following requirements:
Antenna Line on PCB Requirements Characteristic Impedance Max Attenuation 50Ohm 0.3dB Coupling with other signals shall be avoided Cold End (Ground Plane) of antenna shall be equipotential to the CL865 ground pads Furthermore if the device is developed for the US and/or Canada market, it must comply with the FCC and/or IC approval requirements:
This device is to be used only for mobile and fixed application. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-Users must be provided with transmitter operation conditions for satisfying RF exposure compliance.

Antennas used for this OEM module must not exceed 5dBi gain for mobile and fixed operating configurations. 7.1.1. CL865 Antenna PCB line Guidelines When using the Telit CL865 module, since there's no antenna connector on the module, the antenna must be connected to the CL865 through the PCB with the antenna pad (pin 34). In the case that the antenna is not directly developed on the same PCB, hence directly connected at the antenna pad of the CL865, then a PCB line is needed in order to connect with it or with its connector. This transmission line shall fulfill the following requirements:
ANTENNA LINE ON PCB REQUIREMENTS 50 ohm 0,3 dB Impedance Max Attenuation No coupling with other signals allowed Cold End (Ground Plane) of antenna shall be equipotential to the CL865 ground pins This transmission line should be designed according to the following guidelines:
Ensure that the antenna line impedance is 50 ohm;
Keep the antenna line on the PCB as short as possible, since the antenna line loss shall be less than 0,3 dB;
Antenna line must have uniform characteristics, constant cross section; avoid meanders and abrupt curves;
Keep, if possible, one layer of the PCB used only for the Ground plane;
Surround (on the sides, over and under) the antenna line on PCB with Ground, avoid having other signal tracks facing directly the antenna line track;
The ground around the antenna line on PCB has to be strictly connected to the Ground Plane by placing vias every 2mm at least;
Place EM noisy devices as far as possible from CL865 antenna line;
Keep the antenna line far away from the CL865 power supply lines;
If you have EM noisy devices around the PCB hosting the CL865, such as fast switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with Ground planes, or shield it with a metal frame cover. If you don't have EM noisy devices around the PCB of CL865, by using a micro strip on the superficial copper layer for the antenna line, the line attenuation will be lower than a buried one;

PCB Guidelines in case of FCC certification In the case FCC certification is required for an application using CL865, according to FCC KDB 996369 for modular approval requirements, the transmission line has to be similar to that implemented on CL865 interface board and described in the following chapter. 7.2.1. Transmission line design During the design of the CL865 interface board, the placement of components has been chosen properly, in order to keep the line length as short as possible, thus leading to lowest power losses possible. A Grounded Coplanar Waveguide (G-CPW) line has been chosen, since this kind of transmission line ensures good impedance control and can be implemented in an outer PCB layer as needed in this case. A SMA female connector has been used to feed the line. The interface board is realized on a FR4, 4-layers PCB. Substrate material is characterized by relative permittivity r = 4.6 0.4 @ 1 GHz, TanD= 0.019 0.026 @ 1 GHz. A characteristic impedance of nearly 50 is achieved using trace width = 1.1 mm, clearance from coplanar ground plane = 0.3 mm each side. The line uses reference ground plane on layer 3, while copper is removed from layer 2 underneath the line. Height of trace above ground plane is 1.335 mm. Calculated characteristic impedance is 51.6 , estimated line loss is less than 0.1 dB. The line geometry is shown below:

Transmission line measurements HP8753E VNA (Full-2-port calibration) has been used in this measurement session. A calibrated coaxial cable has been soldered at the pad corresponding to CL865 RF output; a SMA connector has been soldered to the board in order to characterize the losses of the transmission line including the connector itself.

RS232 Level Translation In order to interface the Telit CL865 with a PC com port or a RS232 (EIA/TIA-232) application, a level translator is required. This level translator must:
Invert the electrical signal in both directions Change the level from 0/1.8V to +/-15V Actually, the RS232 UART 16450, 16550, 16650 & 16750 chipsets accept signals with lower levels on the RS232 side (EIA/TIA-562), allowing a lower voltage-multiplying ratio on the level translator. Note that the negative signal voltage must be less than 0V and hence some sort of level translation is always required. The simplest way to translate the levels and invert the signal is by using a single chip level translator. There is a multitude of them, differing in the number of drivers and receivers and in the levels (be sure to get a true RS232 level translator not a RS485 or other standards). By convention the driver is the level translator from the 0-1.8V UART to the RS232 level. The receiver is the translator from the RS232 level to 0-1.8V UART. In order to translate the whole set of control lines of the UART you will need:
5 drivers 3 receivers An example of RS232 level adaption circuitry could be accomplished using a MAXIM transceiver (MAX218). In this case the chipset is capable of translating directly from 1.8V to the RS232 levels (Example on 4 signals only).

Audio Section Overview The CL865 provides an analog audio interface and digital audio interface. 10.1. Analog Audio Interface (AVI) The CL865 provides an analog audio interface; one differential input for audio to be transmitted(Uplink) and a balanced output for audio to be received(Downlink). The bias for the microphone has to be as clean as possible; the first connection (single ended) is preferable since the Vmic noise and ground noise are fed into the input as common mode and then rejected. This sounds strange; usually the connection to use in order to reject the common mode is the balanced one. In this situation we have to recall that the microphone is a sound to current transducer, so the resistor is the current to tension transducer, so finally the resistor feeds the input in balanced way even if the configuration, from a microphone point of view, seems to be un-balanced.

MIC Connection CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 2014-03-07 If a balanced way is anyway desired, much more care has to be taken to VMIC noise and ground noise. TIP: Since the J-FET transistor inside the microphone acts as RF-detector-amplifier, ask vendor for a microphone with anti-EMI capacitor (usually a 33pF or a 10pF capacitor placed across the output terminals inside the case).

EAR Connection CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 2014-03-07 The audio output of the CL865 is balanced, this is helpful to double the level and to reject common mode (click and pop are common mode and therefore rejected). These outputs can drive directly a small loudspeaker with electrical impedance not lower than 32Ohm. TIP: in order to get the maximum audio level at a given output voltage level (dBspl/Vrms), the following breaking through procedure can be used. Have the loudspeaker as close as you can to the listener (this simplify also the echo cancelling); choose the loudspeaker with the higher sensitivity (dBspl per W); choose loudspeakers with the impedance close to the limit in order to feed more power inside the transducer (it increases the W/Vrms ratio). If this were not enough, an external amplifier should be used. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

General Purpose I/O The CL865 module is provided by a set of Digital Input / Output pins Input pads can only be read; they report the digital value (high or low) present on the pad at the read time. Output pads can only be written or queried and set the value of the pad output. An alternate function pad is internally controlled by the CL865 firmware and acts depending on the function implemented. The following GPIOs are available on the CL865:

Logic Level Specification Where not specifically stated, all the interface circuits work at 1.8V CMOS logic levels. The following table shows the logic level specifications used in the CL865 interface circuits:
Absolute Maximum Ratings -Not Functional Parameter Input level on any digital pin (CMOS 1.8) with respect to ground Min
-0.3V Max 2.3V Operating Range - Interface levels (1.8V CMOS) Parameter Input high level Input low level Output high level Output low level Min 1.5V 0.0V 1.35V 0.0V Max 2.1V 0.35V 1.8V 0.45V Current characteristics Parameter Output Current Input Current Typical 2mA 30uA 11.2. Using a GPIO Pad as Input The GPIO pads, when used as inputs, can be connected to a digital output of another device and report its status, provided this device has interface levels compatible with the 1.8V CMOS levels of the GPIO. If the digital output of the device to be connected with the GPIO input pad has interface levels different from the 1.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull-up resistor to 1.8V. NOTE:
In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when it is powered OFF or during an ON/OFF transition.

Using a GPIO Pad as Output The GPIO pads, when used as outputs, can drive 1.8V CMOS digital devices or compatible hardware. When set as outputs, the pads have a push-pull output and therefore the pull-up resistor may be omitted. 11.4. Using the Alarm Output GPIO6 The GPIO6 pad, when configured as Alarm Output, is controlled by the CL865 module and will rise when the alarm starts and fall after the issue of a dedicated AT command. This output can be used to controlling microcontroller or application at the alarm time. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

Indication of Network Service Availability The STAT_LED pin status shows information on the network service availability and Call status. In the CL865 modules, the STAT_LED usually needs an external transistor to drive an external LED. Because of the above, the status indicated in the following table is reversed with respect to the pin status:
LED status Device Status Permanently off Fast blinking

The RTC function of CL865 cannot be operated with VRTC only because the RTC section is not an independent part in CL865 unlike other Telits products. So the external RTC backup capacitor will be also useless and VBATT must be connected to the CL865 to use the RTC feature. VRTC is the supply for the internal RTC section and it is generated from VBATT inside the CL865 so the customer must not connect any power supply to the VRTC pin of the CL865. And the customers must not use VRTC for the power supply to any circuits or device in their application board. NOTE:
NO devices must be powered from this pin. WARNING:
For CL865 the RTC feature cannot be operated with VRTC only so VBATT must be connected to the CL865 to use the RTC function. 11.7. VAUX/PWRMON Power Output A regulated power supply output is provided in order to supply small devices from the module. This output is active when the module is ON and goes OFF when the module is shut down. The operating range characteristics of the supply are:

Description CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 2014-03-07 The CL865 module provides a Digital to Analog Converter. The signal (named DAC_OUT) is available on pin 15 of the CL865 module. The on board DAC is in the range from 0 to 1023. However, an external low-pass filter is necessary. Parameter Min Max Units Voltage range (filtered) Range 0 0 1.8 Volt 1023 Steps The precision is 1023 steps, so since the maximum voltage is 1.8V, the integrated voltage could be calculated with the following formula:
Integrated output voltage = 1.8 * value / 1023 DAC_OUT line must be integrated (for example with a low band pass filter) in order to obtain an analog voltage. 12.1.2. Enabling DAC An AT command is available to use the DAC function. The command is: AT#DAC[=<enable>[,<value>]]
<value> - scale factor of the integrated output voltage (0..1023 ~ 10 bit precision) it must be present if <enable>=1 Refer to SW User Guide or AT Commands Reference Guide for the full description of this function. NOTE:
The DAC frequency is selected internally. D/A converter must not be used during POWERSAVING.

Page 58 of 70 Mod. 0805 2011-07 Rev.2 CL865-DUAL Hardware User Guide 1vv0301104 Rev.1 2014-03-07 Holes in pad are allowed only for blind holes and not for through holes. Recommendations for PCB pad surfaces:
Finish Layer thickness [ m]
Electro-less Ni / Immersion Au 3 7 / 0.05 0.15 Properties good solder ability protection, high shear force values The PCB must be able to resist the higher temperatures which are occurring at the lead-free process. This issue should be discussed with the PCB-supplier. Generally, the wettability of tin-
lead solder paste on the described surface plating is better compared to lead-free solder paste. It is not necessary to panel the application PCB, however in that case it is suggested to use milled contours and predrilled board breakouts; scoring or v-cut solutions are not recommended. 13.7. Solder paste Solder paste Lead free Sn/Ag/Cu We recommend using only no clean solder paste in order to avoid the cleaning of the modules after assembly. 13.8.
