Configuration Pins Based on PCI Express M.2 Specification, LN920 has 4 configuration pins: they allow the host to identify the presence of an LN920 data card in the M.2 socket and identify main host interface and port configuration. Signal State Interface Type The state of configuration pins is as follows: Pin 21 69 75 1 CONFIG_0 CONFIG_1 CONFIG_2 CONFIG_3 Table 4: Configuration Pins GND GND NC NC USB 3.1 Gen1 Port Configuration 2 1VV0301730 Rev. 8 Page 12 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide Note: On the host side, each of the CONFIG_0 to CONFIG_4 pins require a pull-up resistor. Based on the configuration pins state on the LN920, being tied to GND or lifted to No Connect (NC), the sensed pins will create a 4-bit logic state. For more details, please refer to PCI Express M.2 standard specifications. 1VV0301730 Rev. 8 Page 13 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide Block Diagram The diagram below shows an overview of the internal architecture of the LN920 data card.

POWER SUPPLY Both power supply circuitry and board layout are a very important parts of the full product design and they strongly reflect on the product overall performances, so the requirements and the guidelines that will follow should be read carefully for a proper design. Power Supply Requirements The LN920 power requirements are as follows:
Power Supply Value Nominal Supply Voltage Supply Voltage Range 3.3V 3.1 V - 3.6 V Maximum ripple on module input supply TBD Table 14: Power Supply Requirements Note: The Operating Voltage Range MUST never be exceeded; the applications power supply section must be designed with care to avoid an excessive voltage drop. If the voltage drop exceeds the limits, it may cause unintentional module power off of LN920. The minimum voltage must be at least VBATTmin to power on the module. Power Consumption Below table provides typical current consumption values of LN920 for various operation modes. 1VV0301730 Rev. 8 Page 28 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 4.2.1.

Electrical design of the power supply Thermal design PCB layout 4.3.1. Electrical Design Guidelines The electrical design of the power supply strongly depends on the power source where this power is drained. We will distinguish them into three categories:
+5V input (typically PC internal regulator output)
+12V input (typically automotive) Battery 4.3.1.1. +5V Source Power Supply Design Guidelines The desired output for the power supply is 3.3V, so the difference between the input and the desired output voltage is limited and a linear regulator can be used. A switching power supply will not be suitable for this application, due to the low drop out requirements. When using a linear regulator, a proper heat sink shall 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 Module, a 100F capacitor is usually suitable. Make sure the low ESR capacitor on the power supply output rated at least 10V. A protection diode must be inserted close to the power input to protect the LN920 module from power polarity inversion. 1VV0301730 Rev. 8 Page 30 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 4.3.2. Thermal Design Guidelines The aim of this chapter is to provide thermal design guidelines useful for developing a product with the LN920. Proper thermal protection design protects against human or component damage for worst-case conditions. Furthermore, it reduces the failure probability and does not adversely affect normal module operation and greatly extends the operation time with maximum performance. For more details, please refer to the dedicated thermal design guideline document. Note: The average consumption during transmission depends on the power level at which device is requested to transmit via the network. Therefore, the average current consumption varies significantly. Note: There is the large solder resist opening area on the bottom side of the module. Adding a TIM on that area with a heatsink is one of the recommended way to dissipate heat. Modem temperature can be read by means of AT commands. Note: For best RF performance, thermal dissipation and mechanical stability, the LN920 must be connected to the ground and metal chassis of the host board. The module shield and host device main board or metal chassis should be connected by means of conductive materials. 4.3.3. Power Supply PCB Layout Guidelines As mentioned in the electrical design guidelines, the power supply shall have a low ESR capacitor on the output to absorb current peaks on the input and protect the supply from voltage spikes. Placement of this component is crucial for the correct working of the 1VV0301730 Rev. 8 Page 31 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide circuitry. A misplaced component can be useless or can even decrease the power supply performances. The Bypass low ESR capacitor must be placed closed to the LN920 power input pins or. In the case the power supply is a switching type, it can be placed close to the inductor to reduce ripple, provided the PCB trace from the capacitor to the LN920 is wide enough to ensure a voltage dropless connection even during an TBD(A) current peaks. The protection diode must be placed close to the input connector where the power source is drained. PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occurs when an TBD A current peak is absorbed. The PCB traces to the LN920 and the Bypass capacitor must be wide enough to ensure no significant voltage drops occurs. This is for the same reason as previous point. Try to keep this trace as short as possible. To reduce EMI due to switching, it is important to keep the mesh involved very small; therefore the input capacitor, the output diode (if not embodied in the IC) and the regulator, shall form a very small loop. This is done in order to reduce the radiated field (noise) at the switching frequency (100-500 kHz usually). Power supply placement on the board should be designed to guarantee that the high current return paths on the ground plane are not overlapping to any noise sensitive circuitry, such as audio amplifiers etc. The power supply input cables should be kept separate from noise sensitive lines such as microphone/earphone cables. RTC (Real Time Clock) The RTC function is provided to keep time information with low power consumption even when the LN920 is turned off. It is also provided to enable alarm wake-up when the LN920 is turned off. 1VV0301730 Rev. 8 Page 32 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 5.

Only USIM interfaces support dual voltage I/O levels. The following tables show logic level specifications used in the LN920 interface circuits. The data specified in the tables below are valid throughout the operating voltage and temperature range. Warning: Do not connect LN920s digital logic signal directly to host digital signals with a voltage higher than 2.3V for 1.8V CMOS signals LN920 has four main operation states:
OFF state: Vbatt is applied and only RTC is running. Baseband is switched OFF and the only transition possible is the ON state. ON state: Baseband is fully switched on and LN920 is ready to respond to AT commands. The modem can be idle or connected. Sleep mode state: Main baseband processor is intermittently switched ON and AT commands can be processed with some latency. LN920 is idle with low current consumption. Deep sleep mode state: PSM (Power Saving Mode) as defined in 3GPP Release 12. Baseband circuitry is switched OFF most of the time. Note: Throughout this document, all lines that are inverted, that is are active low, are labelled with a name ending with#",* or with a bar above the name. 1VV0301730 Rev. 8 Page 34 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide Logic Levels Parameter Min Max ABSOLUTE MAXIMUM RATINGS NOT FUNCTIONAL Input level on any digital pin (CMOS 1.8) with respect to ground

Initialization and Activation State After turning on the LN920, the module is not instantly activated because the SW initialization process takes some time to complete. For this reason, it is recommended not to communicate with the LN920 during this initialization phase. When the AT command interface is accessible via USB port, the device might not be yet fully operational. In general, as shown in below figure, the LN920 becomes fully operational (in the Activation State) at least 50 seconds after the FULL_CARD_POWER_OFF# line is asserted. Figure 3: LN920 Initialization and Activation As shown in the diagram above, Boot OK* pin will indicate when the module is activated. 1VV0301730 Rev. 8 Page 36 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide When the line status transitions to high, the module has completed boot up.
* Boot OK (Shutdown indicator) is an optional function and is disabled by default. Host can use the AT#SHDNIND command to assign one of the GPIOs as the Boot OK pin. After enabling the function, the corresponding pin operates as a Book OK and also Shutdown Indicator function. Please refer to the Power Off chatper for more information regarding Shutdown indicator. Please refer to the AT Reference guide document for more details about AT#SHDNIND command. Note: To avoid back-powering effect, it is recommended to avoid applying HIGH logic level signals applied to the module digital pins when it is powered OFF or during an ON/OFF transition. Power Off Turning off of the device can be performed in two ways:
Graceful shutdown by means of FULL_CARD_POWER_OFF# line Fast Shutdown by GPIO triggered Warning: Not following the recommended shut-down procedures might damage the device and consequently void the warranty. 1VV0301730 Rev. 8 Page 37 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 6.3.1. Graceful Shutdown To safely power off the LN920 module, the host can use the graceful shutdown function. To gracefully shutdown the LN920 module, FULL_CARD_POEWR_OFF# should be asserted Low. Once FULL_CARD_POWER_OFF# is asserted LOW, the LN920 module enters finalization state, terminates active processes and prepare to turn off safely. As shown in the diagram below, Shutdown Indicator* pin will indicate when the module has completed turned off. When the status transitions to Low, the module has completed shutdown procedure. Figure 4: Graceful Shutdown by FULL_CARD_POWER_OFF_N
* Shutdown Indicator (Boot OK) is optional function and is disabled by default. The host can use the AT#SHDNIND command to assign one of the GPIOs as the Shutdown Indicator pin. After enabling the function, the corresponding pin operates as a Shutdown Indicator and also Boot OK function. About Boot OK, please refer to the Power On chapter. Refer to the AT Reference guide document for more details about AT#SHDNIND. 6.3.2. Fast Shutdown For a quicker shutdown of the LN920 module, the host can use the fast shutdown function. If properly configured, one of GPIO lines can be used as Fast Shutdown** Trigger. 1VV0301730 Rev. 8 Page 38 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide Once the Fast Shutdown Trigger senses a HIGH to LOW transition, fast shutdown is triggered. Then the LN920 module enters finalization state, it terminates active processes and prepares to turn off safely. As shown in the diagram below, when the module is ready to be turned off, it will be indicated via Shutdown Indicator*. When the status transitions to Low, the module is ready to shutdown.
* Shutdown Indicator (Boot OK) is optional function and is disabled by default. Host can use the AT#SHDNIND command to assign one of the GPIOs as the Shutdown Indicator pin. After enabling the function, the corresponding pin operates as a Shutdown Indicator and also Boot OK function. About Boot OK, please refer to the Power On chatper. Refer to the AT Reference guide document for more details about AT#SHDNIND.
** Fast Shutdown is optional function and is disabled by default. Host can use the AT#FASTSHDN command to assign one of the GPIOs as the Fast Shutdown Trigger pin. After enabling the function, Fast shutdown will be triggered by HIGH to LOW transition through corresponding pin. Refer to the AT Reference guide document for more details about and AT#FASTSHDN. Fast shutdown by GPIO Figure 5: Fast Shutdown by GPIO Warning: If VPH_PWR is still supplied after Fast Shutdown is completed, the module will re-start Power On procedure. Because the Power On is triggered again by FULL_CARD_POWER_OFF_N. To avoid this, enable the Shutdown indicator function. 1VV0301730 Rev. 8 Page 39 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide RESET Device reset can be triggered by Unconditional reset using the RESET#. 6.4.1. Unconditional Hardware Reset To unconditionally restart the LN920 module, the RESET# pin must be asserted LOW for more than 1 second, then released. As shown in the diagram below, Boot OK/ Shutdown Indicator* pin will indicate module status. When the status transitions High to Low, the module has completed power off procedure. When the status transitions Low to High, the module has completed power on procedure. Figure 6: Unconditional Hardware Reset by SYS_RESIN_N Pad
* Boot OK/ Shutdown Indicator (Boot OK) is optional function and is disabled by default. Host can use the AT#SHDNIND command to assign one of the GPIOs as the Boot OK/
Shutdown Indicator pin. After enabling the function, the corresponding pin operates as a Boot OK and Shutdown Indicator function. Refer to the AT Reference guide document for more details about AT#SHDNIND. Note: Unconditional Hardware Reset must be used only as an emergency procedure, not as a normal power-off operation. 1VV0301730 Rev. 8 Page 40 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide Note: Do not use any pull-up resistor on the RESET# line or any other totem pole digital output. Using a pull-up resistor may cause latch-
up problems on the LN920 power regulator and incorrect module operation. The RESET# line must be connected only in an open-collector configuration. Below figure shows a simple circuit for this action.

It is compliant with Universal Serial Bus Specifications, Revision 3.0 and can be used for control and data transfers as well as for diagnostic monitoring and firmware update. The USB port is the main interface between the LN920 module and the host controlling the modem hardware. 1VV0301730 Rev. 8 Page 41 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide USB 3.0 needs AC coupling series capacitors on the TX lines in both directions. In order to interface USB3.0 with the application board controlling the modem, 0.1uF capacitors should be installed on USB_SS_RX_P/M lines of the LN920. Series capacitors are already placed on USB_SS_TX_P/M lines inside LN920 module.

When VDD is 3.3V and LEDs forward voltage is 2.0V, it is recommended to use the value of R1 from 66 ohm to 250 Ohm. However, the resistor value must be calculated considering LED characteristics. If WWAN LED function is enabled by means of the Note:

Using a GPIO as INPUT The GPIO pins, when used as inputs, can be connected to the digital output of another device and report its status, provided that 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 pin of LN920 has interface levels different from the 1.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull up to 1.8V. Note: In order to avoid a back powering effect, it is recommended to prevent any HIGH logic level signal from being applied to the digital pins of the LN920 when the module is powered off or during an ON/OFF transition. Refer to LN920 AT command reference guide for GPIO pins configuration. 1VV0301730 Rev. 8 Page 46 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 6.5.4.2. Using a GPIO as OUTPUT The GPIO pins, when used as outputs, can drive 1.8V CMOS digital devices or compatible hardware. When set as outputs, the pins have a push-pull output, therefore the pull-up resistor may be omitted.

Antenna Cable Connecting cables between the module and the LTE/WCDMA antenna must have 50 impedance. If the impedance of the module does not match, RF performance is significantly reduced. Minimize Antenna Cable Recommendations Item Value Impedance 50 Ohm Max cable loss Less than 0.5 dB Avoid coupling with other signals. Table 33: Minimize Antenna Cable Recommendations Warning: Impedence of RF connector and RF cable must be matched to 50 Ohm. Impedance mismatching will cause poor RF performance,especially i.e. RF cable with high insertion loss will affect on Tx power and Rx sensitivity. 1VV0301730 Rev. 8 Page 53 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 7.4.2.2. Antenna Installation Guidelines Each antenna must be installed with 20dB isolation. Install the antenna in a location with access to the network radio signal. The Antenna must not be installed inside metal cases. The Antenna must be installed according Antenna manufacturer instructions. Antenna integration should optimize the Radiation Efficiency. Efficiency values >
50% are recommended on all frequency bands. Antenna integration should not perturb the radiation pattern described in the Antenna manufacturer documentation. It is preferable to get an omnidirectional radiation pattern. In order to meet the related EIRP limitations, antenna gain must not exceed the values indicated in regulatory requirements, where applicable. The Typical antenna Gain in most M2M applications does not exceed 2dBi. If the device antenna is located farther than 20 cm from the human body and there are no co-located transmitters, then the Telit FCC/IC approvals can be re-used by the end product. If the device antenna is located closer than 20 cm from the human body or there are co-located transmitters, then additional FCC/IC testing may be required for the end product (Telit FCC/IC approvals cannot be reused). Note: GNSS receive path uses either the dedicated GNSS connector or the shared Secondary AUX antenna connector. 1VV0301730 Rev. 8 Page 54 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 8. GNSS SECTION The LN920 module includes a state-of-art receiver that can simultaneously search and track satellite signals from multiple satellite constellations. This multi-GNSS receiver uses the entire spectrum of GNSS systems available: GPS, GLONASS, Beidou, Galileo. RF Front End Design The LN920 GNSS receiver contains an integrated LNA and pre-select SAW filter. This allows the module to work properly with a passive GNSS antenna. If the antenna cannot be located near the module, then an active antenna (that is, an antenna with a low noise amplifier built-in) can be used with an external dedicated power supply circuit. 8.1.1. Guidelines of PCB Line for GNSS Antenna The following guidelines should be followed when choosing and integrating a GNSS antenna:
Make sure that the antenna line impedance is 50 Keep the antenna line on the PCB as short as possible to reduce losses. Antenna line must have uniform characteristics, constant cross section, avoid meanders and abrupt curves. If possible, keep one layer of the PCB used only for the Ground plane. Surround (on both sides, above and below) the antenna line on PCB with Ground, avoid having other signal tracks facing directly the antenna line. The ground around the antenna line on PCB must be strictly connected to the Ground Plane by placing away once per 2mm at least. Place EM noisy devices as far as possible from antenna line. Keep the antenna line as far as possible from power supply lines. Keep the antenna line far away from cellular RF lines. If there are noisy EM devices around the PCB hosting the module, such as fast switching ICs, shield antenna line by burying it inside the layers of PCB and surrounding it with ground planes, or shielding it with a metal frame cover. If there are no noisy EM devices around the PCB hosting the module, use a strip-
line on the superficial copper layer for the antenna line. The line attenuation will be lower than a buried one. 1VV0301730 Rev. 8 Page 55 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 8.1.2. Hardware-Based Solution for GNSS and LTE Coexistence When a stand-alone GNSS receiver is present in the user application, the transmitted LTE signal may desensitize the GNSS receiver, especially if decoupling between the LTE and GNSS antennas is low. A SAW filter can be added on LTE side to protect the GNSS receiver from LTE out-of-band emissions, as described in the schematic below. When the GNSS receiver embedded in the LN920 module is used, the LTE transmitter and the GNSS receiver are never simultaneously active, thus filtering on the LTE side is not needed. Figure 15: Reference schematic GNSS Antenna Requirements For most applications, it is recommented to use an active GNSS antenna. 8.2.1.

In case of long RF cable the gain must be increased up to 30dB. 8.2.2. GNSS Antenna Installation Guidelines The antenna must be installed according to the antenna manufacturers instructions to obtain the maximum performance from the GNSS receiver. The position of the antenna must be carefully evaluated if operating in conjunction with any other antenna or transmitter. The antenna must not be installed inside metal cases or near any obstacle that may degrade features such as antenna lobes and gain.

APPLICATION GUIDE Debug of the LN920 Module in Production To test and debug the LN920 module integration, it is strongly recommended to add test points on the host PCB for the following purposes:
Checking the connection between the LN920 itself and the application Testing module performance by connecting it to an external computer Depending on the customer application, these test pins include, but are not limited to, the following signals:
RESET#, W_DISABLE1#
VBATT, GND USB_D-, USB_D+
USB3.0_TX-, USB3.0_TX+, USB3.0_RX-, USB3.0_RX+
In addition, the following signals are also recommended (but not mandatory):
GPS_DISABLE#, WOW#, WWAN_LED#
GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 Bypass Capacitor on Power Supplies When a sudden power supply voltage variation or interruption, the steep transition causes effects such as overshoot and undershoot. This abrupt voltage transition can affect the device causing it to not operate or to malfunction. Bypass capacitors are needed to prevent issues: special attention to this issue must be paid when designing the application board. The length and width of the power lines must be carefully dimensioned, and capacitors value must be selected accordingly. The capacitor will also prevent power supplies ripple and the switching noise caused in TDMA systems. Most important, a suitable bypass capacitor must be mounted on the following lines on the application board:
VBATT Recommended values are:
100uF for VBATT 1VV0301730 Rev. 8 Page 59 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide considerate must be kept into account that the capacitance mainly depends on the application board. Generally, additional capacitance is required when the power line is longer. And if fast power down function is used, additional bypass capacitors should be mounted on the application board. EMC Recommendations EMC protection on all the pins of LN920 should be designed by application side according to the customers requirement. ESD rating on all pins of LN920 Family :
Human Body Model (HBM): 1000 V Charged Device Model (CDM): 250 V All Antenna pins up to 4 kV Warning: Do not touch the modem without proper electrostatic protective equipment. The product must be handled with care, avoiding any contact with the pins because electrostatic discharge may damage the product itself. 1VV0301730 Rev. 8 Page 60 of 81 2022-03-03 Not Subject to NDA LN920 HW Design Guide 11.

Do not disassemble the product; any mark of tampering will compromise the warranty validity. We recommend following the instructions of the hardware user guides for correct wiring of the product. The product has to be supplied with a stabilized voltage source and the wiring has to be conformed to the security and fire prevention regulations. The product has to be handled with care, avoiding any contact with the pins because electrostatic discharges may damage the product itself. Same cautions have to be taken for the SIM, checking carefully the instruction for its use. Do not insert or remove the SIM when the product is in power saving mode. The system integrator is responsible for the functioning of the final product. Therefore, the external components of the module, as well as any project or installation issue, have to be handled with care. Any interference may cause the risk of disturbing the GSM network or external devices or having an impact on the security system. Should there be any doubt, please refer to the technical documentation and the regulations in force. Every module has to be equipped with a proper antenna with specific characteristics. The antenna has to be installed carefully in order to avoid any interference with other electronic devices and has to guarantee a minimum distance from the body (20 cm). In case this requirement cannot be satisfied, the system integrator has to assess the final product against the SAR regulation. The equipment is intended to be installed in a restricted area location. The equipment must be supplied by an external specific limited power source in compliance with the standard EN 62368-1:2014.
