This document can help customers quickly understand module interface specifications, electrical and mechanical details, as well as other related information of EG95 module. Associated with application note and user guide, customers can use EG95 module to design and set up mobile applications easily. EG95_Hardware_Design 9 / 81 LTE Module Series EG95 Hardware Design 1.1. Safety Information The following safety precautions must be observed during all phases of operation, such as usage, service or repair of any cellular terminal or mobile incorporating EG95 module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel, and incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for customers failure to comply with these precautions. Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) causes distraction and can lead to an accident. You must comply with laws and regulations restricting the use of wireless devices while driving. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden, so as to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers an Airplane Mode which must be enabled prior to boarding an aircraft. Switch off your wireless device when in hospitals,clinics or other health care facilities. These requests are designed to prevent possible interference with sensitive medical equipment. Cellular terminals or mobiles operating over radio frequency signal and cellular network cannot be guaranteed to connect in all conditions, for example no mobile fee or with an invalid (U)SIM card. While you are in this condition and need emergent help, please remember using emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Your cellular terminal or mobile contains a transmitter and receiver. When it is ON, it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment. In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potentially explosive atmospheres include fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders, etc. EG95_Hardware_Design 10 / 81 LTE Module Series EG95 Hardware Design 2 Product Concept 2.1.

Operating Modes The table below briefly summarizes the various operating modes referred in the following chapters. Table 5: Overview of Operating Modes Mode Details Normal Operation Minimum Functionality Mode Airplane Mode Idle Talk/Data Software is active. The module has registered on network, and it is ready to send and receive data. Network connection is ongoing. In this mode, the power consumption is decided by network setting and data transfer rate. AT+CFUN command can set the module to a minimum functionality mode without removing the power supply. In this case, both RF function and (U)SIM card will be invalid. AT+CFUN command or W_DISABLE# pin can set the module to airplane mode. In this case, RF function will be invalid. In this mode, the current consumption of the module will be reduced to the minimal level. Sleep Mode During this mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the network normally. In this mode, the power management unit shuts down the power supply. Software is not active. The serial interface is not accessible. Operating voltage (connected to VBAT_RF and VBAT_BB) remains applied. Power Down Mode 3.5. Power Saving 3.5.1. Sleep Mode EG95 is able to reduce its current consumption to a minimum value during the sleep mode. The following sections describe the power saving procedures of EG95 module. EG95_Hardware_Design 24 / 81 LTE Module Series EG95 Hardware Design 3.5.1.1. UART Application If the host communicates with the module via UART interface, the following preconditions can let the module enter into sleep mode. Execute AT+QSCLK=1 command to enable sleep mode. Drive DTR to high level. The following figure shows the connection between the module and the host. Figure 3: Sleep Mode Application via UART Driving the host DTR to low level will wake up the module. When EG95 has a URC to report, RI signal will wake up the host. Refer to Chapter 3.16 for details about RI behavior. AP_READY will detect the sleep state of host (can be configured to high level or low level detection). Please refer to AT+QCFG="apready"* command for details. NOTE
* means under development. 3.5.1.2. USB Application with USB Remote Wakeup Function If the host supports USB suspend/resume and remote wakeup functions, the following three preconditions must be met to let the module enter into sleep mode. Execute AT+QSCLK=1 command to enable the sleep mode. Ensure the DTR is held at high level or keep it open. The hosts USB bus, which is connected with the modules USB interface, enters into suspended state. EG95_Hardware_Design 25 / 81 RXDTXDRIDTRAP_READYTXDRXDEINTGPIOGPIOModuleHostGNDGND LTE Module Series EG95 Hardware Design The following figure shows the connection between the module and the host. Figure 4: Sleep Mode Application with USB Remote Wakeup Sending data to EG95 through USB will wake up the module. When EG95 has a URC to report, the module will send remote wake-up signals via USB bus so as to wake up the host. 3.5.1.3. USB Application with USB Suspend/Resume and RI Function If the host supports USB suspend/resume, but does not support remote wake-up function, the RI signal is needed to wake up the host. There are three preconditions to let the module enter into the sleep mode. Execute AT+QSCLK=1 command to enable sleep mode. Ensure the DTR is held at high level or keep it open. The hosts USB bus, which is connected with the modules USB interface, enters into suspended state. The following figure shows the connection between the module and the host.

When EG95 has a URC to report, RI signal will wake up the host. 3.5.1.4. USB Application without USB Suspend Function If the host does not support USB suspend function, USB_VBUS should be disconnected with an external control circuit to let the module enter into sleep mode. Execute AT+QSCLK=1 command to enable the sleep mode. Ensure the DTR is held at high level or keep it open. Disconnect USB_VBUS. The following figure shows the connection between the module and the host. Figure 6: Sleep Mode Application without Suspend Function Switching on the power switch to supply power to USB_VBUS will wake up the module. NOTE Please pay attention to the level match shown in dotted line between the module and the host. Refer to document [1] for more details about EG95 power management application. 3.5.2. Airplane Mode When the module enters into airplane mode, the RF function does not work, and all AT commands correlative with RF function will be inaccessible. This mode can be set via the following ways. Hardware:
The W_DISABLE# pin is pulled up by default. Driving it to low level will let the module enter into airplane mode. EG95_Hardware_Design 27 / 81 USB_VBUSUSB_DPUSB_DMAP_READYVDDUSB_DPUSB_DMGPIOModuleHostRIEINTPower SwitchGPIOGNDGND LTE Module Series EG95 Hardware Design Software:
AT+CFUN command provides the choice of functionality levels as shown below:
AT+CFUN=0: Minimum functionality mode. Both (U)SIM and RF functions are disabled. AT+CFUN=1: Full functionality mode (by default). AT+CFUN=4: Airplane mode. RF function is disabled. NOTES 1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled by AT+QCFG="airplanecontrol" command and this command is under development. 2. The execution of AT+CFUN command will not affect GNSS function. 3.6. Power Supply 3.6.1. Power Supply Pins EG95 provides four VBAT pins for connection with an external power supply. There are two separate voltage domains for VBAT. Two VBAT_RF pins for modules RF part. Two VBAT_BB pins for modules baseband part. The following table shows the details of VBAT pins and ground pins.

Please make sure that the input voltage will never drop below 3.3V. The following figure shows the voltage drop during burst transmission in 2G network. The voltage drop will be less in 3G and 4G networks. Figure 7: Power Supply Limits during Burst Transmission To decrease voltage drop, a bypass capacitor of about 100F with low ESR (ESR=0.7) should be used, and a multi-layer ceramic chip (MLCC) capacitor array should also be reserved due to its ultra-low ESR. It is recommended to use three ceramic capacitors (100nF, 33pF, 10pF) for composing the MLCC array, and place these capacitors close to VBAT_BB/VBAT_RF pins. The main power supply from an external application has to be a single voltage source and can be expanded to two sub paths with star structure. The width of VBAT_BB trace should be no less than 1mm, and the width of VBAT_RF trace should be no less than 2mm. In principle, the longer the VBAT trace is, the wider it will be. In addition, in order to get a stable power source, it is suggested that a zener diode whose dissipation power is more than 0.5W should be used. The following figure shows the star structure of the power supply. Figure 8: Star Structure of the Power Supply EG95_Hardware_Design 29 / 81 VBATMin.3.3VRippleDropBurst TransmissionBurst TransmissionModuleVBAT_RFVBAT_BBVBATC1100uFC6100nFC733pFC810pF++C2100nFC5100uFC333pFC410pFD1 LTE Module Series EG95 Hardware Design 3.6.3. Reference Design for Power Supply Power design for the module is very important, as the performance of the module largely depends on the power source. The power supply should be able to provide sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested that an LDO should be used to supply power for the module. If there is a big voltage difference between the input source and the desired output (VBAT), a buck converter is preferred to be used as the power supply. The following figure shows a reference design for +5V input power source. The typical output of the power supply is about 3.8V and the maximum load current is 3A. Figure 9: Reference Circuit of Power Supply NOTE In order to avoid damaging internal flash, please do not switch off the power supply when the module works normally. Only after the module is shut down by PWRKEY or AT command, the power supply can be cut off. 3.6.4. Monitor the Power Supply AT+CBC command can be used to monitor the VBAT_BB voltage value. For more details, please refer to document [2]. 3.7. Turn on and off Scenarios 3.7.1. Turn on Module Using the PWRKEY The following table shows the pin definition of PWRKEY.

When EG95 is in power down mode, it can be turned on to normal mode by driving the PWRKEY pin to a low level for at least 500ms. It is recommended to use an open drain/collector driver to control the PWRKEY. After STATUS pin outputting a high level, PWRKEY pin can be released. A simple reference circuit is illustrated in the following figure. Figure 10: Turn on the Module Using Driving Circuit Another way to control the PWRKEY is using a button directly. When pressing the key, electrostatic strike may generate from the finger. Therefore, a TVS component is indispensable to be placed nearby the button for ESD protection. A reference circuit is shown in the following figure.

Figure 12: Timing of Turning on Module NOTE Please make sure that VBAT is stable before pulling down PWRKEY pin. The time between them is no less than 30ms. 3.7.2. Turn off Module Either of the following methods can be used to turn off the module:
Normal power down procedure: Turn off the module using the PWRKEY pin. Normal power down procedure: Turn off the module using AT+QPOWD command. 3.7.2.1. Turn off Module Using the PWRKEY Pin Driving the PWRKEY pin to a low level voltage for at least 650ms, the module will execute power-down procedure after the PWRKEY is released. The power-down scenario is illustrated in the following figure.

Turn off Module Using AT Command It is also a safe way to use AT+QPOWD command to turn off the module, which is similar to turning off the module via PWRKEY pin. Please refer to document [2] for details about the AT+QPOWD command. NOTE In order to avoid damaging internal flash, please do not switch off the power supply when the module works normally. Only after the module is shut down by PWRKEY or AT command, the power supply can be cut off. 3.8. Reset the Module The RESET_N pin can be used to reset the module.

(U)SIM Interfaces EG95 provides two (U)SIM interfaces, and only one (U)SIM card can work at a time. The (U)SIM 1 and
(U)SIM 2 cards can be switched by AT+QDSIM command. For more details, please refer to document

Keep placement of (U)SIM card connector to the module as close as possible. Keep the trace length as less than 200mm as possible. Keep (U)SIM card signals away from RF and VBAT traces. Assure the ground between the module and the (U)SIM card connector short and wide. Keep the trace width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and shield them with surrounded ground. In order to offer good ESD protection, it is recommended to add a TVS diode array whose parasitic capacitance should not exceed 15pF. The 0 resistors should be added in series between the module and the (U)SIM card so as to suppress EMI spurious transmission and enhance ESD protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the
(U)SIM peripheral circuit should be close to the (U)SIM card connector. The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion are applied, and should be placed close to the (U)SIM card connector. 3.10. USB Interface EG95 contains one integrated Universal Serial Bus (USB) interface which complies with the USB 2.0 specification and supports high-speed (480Mbps) and full-speed (12Mbps) modes. The USB interface is used for AT command communication, data transmission, GNSS NMEA sentences output, software debugging, firmware upgrade and voice over USB*. The following table shows the pin definition of USB interface.

EG95_Hardware_Design 38 / 81 LTE Module Series EG95 Hardware Design The USB interface is recommended to be reserved for firmware upgrade in customers design. The following figure shows a reference circuit of USB interface. Figure 21: Reference Circuit of USB Interface A common mode choke L1 is recommended to be added in series between the module and customers MCU in order to suppress EMI spurious transmission. Meanwhile, the 0 resistors (R3 and R4) should be added in series between the module and the test points so as to facilitate debugging, and the resistors are not mounted by default. In order to ensure the integrity of USB data line signal, L1/R3/R4 components must be placed close to the module, and also these resistors should be placed close to each other. The extra stubs of trace must be as short as possible. The following principles should be complied with when design the USB interface, so as to meet USB 2.0 specification. It is important to route the USB signal traces as differential pairs with total grounding. The impedance of USB differential trace is 90. Do not route signal traces under crystals, oscillators, magnetic devices and RF signal traces. It is important to route the USB differential traces in inner-layer with ground shielding on not only upper and lower layers but also right and left sides. Pay attention to the influence of junction capacitance of ESD protection component on USB data lines. Typically, the capacitance value should be less than 2pF. Keep the ESD protection components to the USB connector as close as possible. NOTES 1. EG95 module can only be used as a slave device. 2. * means under development.

PCM and I2C Interfaces EG95 provides one Pulse Code Modulation (PCM) digital interface for audio design, which supports the following modes and one I2C interface:
Primary mode (short frame synchronization, works as both master and slave) Auxiliary mode (long frame synchronization, works as master only) In primary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge. The PCM_SYNC falling edge represents the MSB. In this mode, the PCM interface supports 256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK at 8kHz PCM_SYNC, and also supports 4096kHz PCM_CLK at 16kHz PCM_SYNC. In auxiliary mode, the data is also sampled on the falling edge of the PCM_CLK and transmitted on the rising edge. The PCM_SYNC rising edge represents the MSB. In this mode, the PCM interface operates with a 256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK and an 8kHz, 50% duty cycle PCM_SYNC. EG95 supports 16-bit linear data format. The following figures show the primary modes timing relationship with 8KHz PCM_SYNC and 2048KHz PCM_CLK, as well as the auxiliary modes timing relationship with 8KHz PCM_SYNC and 256KHz PCM_CLK.

Layout Guidelines The following layout guidelines should be taken into account in customers design. Maximize the distance among GNSS antenna, main antenna and Rx-diversity antenna. Digital circuits such as (U)SIM card, USB interface, camera module and display connector should be kept away from the antennas. Use ground vias around the GNSS trace and sensitive analog signal traces to provide coplanar isolation and protection. Keep the characteristic impedance for ANT_GNSS trace as 50. Please refer to Chapter 5 for GNSS reference design and antenna installation information. EG95_Hardware_Design 49 / 81 LTE Module Series EG95 Hardware Design 5 Antenna Interfaces EG95 antenna interfaces include a main antenna interface and an Rx-diversity antenna interface which is used to resist the fall of signals caused by high speed movement and multipath effect, and a GNSS antenna interface which is only supported on EG95-NA.

Keep a proper distance between the main antenna and the Rx-diversity antenna to improve the receiving sensitivity. 2. ANT_DIV function is enabled by default. AT+QCFG="diversity",0 command can be used to disable receive diversity. 3. Place the -type matching components (R1/C1/C2, R2/C3/C4) as close to the antenna as possible. 5.1.4. Reference Design of RF Layout For users PCB, the characteristic impedance of all RF traces should be controlled as 50. The impedance of the RF traces is usually determined by the trace width (W), the materials dielectric constant, the distance between signal layer and reference ground (H), and the clearance between RF trace and ground (S). Microstrip line or coplanar waveguide line is typically used in RF layout for characteristic impedance control. The following are reference designs of microstrip line or coplanar waveguide line with different PCB structures. Figure 31: Microstrip Line Design on a 2-layer PCB Figure 32: Coplanar Waveguide Line Design on a 2-layer PCB EG95_Hardware_Design 52 / 81 LTE Module Series EG95 Hardware Design Figure 33: Coplanar Waveguide Line Design on a 4-layer PCB (Layer 3 as Reference Ground) Figure 34: Coplanar Waveguide Line Design on a 4-layer PCB (Layer 4 as Reference Ground) In order to ensure RF performance and reliability, the following principles should be complied with in RF layout design:
Use impedance simulation tool to control the characteristic impedance of RF traces as 50. The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully connected to ground. The distance between the RF pins and the RF connector should be as short as possible, and all the right angle traces should be changed to curved ones. There should be clearance area under the signal pin of the antenna connector or solder joint. The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be no less than two times the width of RF signal traces (2*W). For more details about RF layout, please refer to document [4].

Consequently, it is subject to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates the module. The following table shows the modules electrostatic discharge characteristics. Table 35: Electrostatic Discharge Characteristics Tested Points Contact Discharge Air Discharge Unit VBAT, GND All Antenna Interfaces 5 4 Other Interfaces 0.5 10 8 1 KV KV KV EG95_Hardware_Design 65 / 81 LTE Module Series EG95 Hardware Design 6.8. Thermal Consideration In order to achieve better performance of the module, it is recommended to comply with the following principles for thermal consideration:
On customers PCB design, please keep placement of the module away from heating sources, especially high power components such as ARM processor, audio power amplifier, power supply, etc. Do not place components on the opposite side of the PCB area where the module is mounted, in order to facilitate adding of heatsink when necessary. Do not apply solder mask on the opposite side of the PCB area where the module is mounted, so as to ensure better heat dissipation performance. The reference ground of the area where the module is mounted should be complete, and add ground vias as many as possible for better heat dissipation. Make sure the ground pads of the module and PCB are fully connected. According to customers application demands, the heatsink can be mounted on the top of the module, or the opposite side of the PCB area where the module is mounted, or both of them. The heatsink should be designed with as many fins as possible to increase heat dissipation area. Meanwhile, a thermal pad with high thermal conductivity should be used between the heatsink and module/PCB. The size of the heatsink should be larger than that of the modules shielding cover to avoid the deformation of the shielding cover. The following shows two kinds of heatsink designs for reference and customers can choose one or both of them according to their application structure. Figure 39: Referenced Heatsink Design (Heatsink at the Top of the Module) EG95_Hardware_Design 66 / 81 HeatsinkEG95 ModuleApplication BoardApplication BoardHeatsinkThermal PadShielding Cover LTE Module Series EG95 Hardware Design Figure 40: Referenced Heatsink Design (Heatsink at the Bottom of Customers PCB) NOTE The module offers the best performance when the internal BB chip stays below 105C. When the maximum temperature of the BB chip reaches or exceeds 105C, the module works normal but provides reduced performance (such as RF output power, data rate, etc.). When the maximum BB chip temperature reaches or exceeds 115C, the module will disconnect from the network, and it will recover to network connected state after the maximum temperature falls below 115C. Therefore, the thermal design should be maximally optimized to make sure the maximum BB chip temperature always maintains below 105C. Customers can execute AT+QTEMP command and get the maximum BB chip temperature from the first returned value.

Storage EG95 is stored in a vacuum-sealed bag. The storage restrictions are shown as below. 1. Shelf life in the vacuum-sealed bag: 12 months at <40C/90%RH. 2. After the vacuum-sealed bag is opened, devices that will be subjected to reflow soldering or other high temperature processes must be:
Mounted within 168 hours at the factory environment of 30C/60%RH. Stored at <10%RH. 3. Devices require baking before mounting, if any circumstance below occurs. When the ambient temperature is 23C5C and the humidity indication card shows the humidity is >10% before opening the vacuum-sealed bag. Device mounting cannot be finished within 168 hours at factory conditions of 30C/60%RH. 4. If baking is required, devices may be baked for 8 hours at 120C5C. NOTE As the plastic package cannot be subjected to high temperature, it should be removed from devices before high temperature (120C) baking. If shorter baking time is desired, please refer to IPC/JEDECJ-STD-033 for baking procedure. EG95_Hardware_Design 72 / 81 LTE Module Series EG95 Hardware Design 8.2. Manufacturing and Soldering Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. The force on the squeegee should be adjusted properly so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil for the module is recommended to be 0.18mm. For more details, please refer to document [3]. It is suggested that the peak reflow temperature is 235C~245C (for SnAg3.0Cu0.5 alloy). The absolute maximum reflow temperature is 260C. To avoid damage to the module caused by repeated heating, it is suggested that the module should be mounted after reflow soldering for the other side of PCB has been completed. Recommended reflow soldering thermal profile is shown below:
