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 EM120R-GL&EM160R-GL modules. Manufacturers of the cellular terminal should notify users and operating personnel of the following safety information by incorporating these guidelines into all manuals of the product. Otherwise, Quectel assumes no liability for customers failure to comply with these precautions. Full attention must be paid 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. Please comply with laws and regulations restricting the use of wireless devices while driving. Switch off the cellular terminal or mobile before boarding an aircraft. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. If there is an Airplane Mode, it should be enabled prior to boarding an aircraft. Please consult the airline staff for more restrictions on the use of wireless devices on an aircraft. Wireless devices may cause interference on sensitive medical equipment, so please be aware of the restrictions on the use of wireless devices when in hospitals, clinics or other healthcare facilities. Cellular terminals or mobiles operating over radio signals and cellular network cannot be guaranteed to connect in all possible conditions (for example, with unpaid bills or with an invalid (U)SIM card). When emergent help is needed in such conditions, use emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on in a service area with adequate cellular signal strength. The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it receives and transmits radio frequency signals. 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 mobile phone or other cellular terminals. Areas with potentially explosive atmospheres include fueling 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.

Decrease Voltage Drop Power Domain Description 3.1354.4 V 3.7 V typical DC supply Ground The power supply range of the module is from 3.135 V to 4.4 V. Make sure that the input voltage never drops below 3.135 V, otherwise the module will be powered off automatically. The following figure shows the maximum voltage drop during radio transmission in 3G and 4G networks. Figure 3: Power Supply Limits during Radio Transmission To decrease voltage drop, a bypass capacitor of about 220 F with low ESR (ESR = 0.7 ) should be used, and a multi-layer ceramic chip capacitor (MLCC) array should also be reserved due to its ultra-low ESR. It is recommended to use three ceramic capacitors (100 nF, 33 pF, 10 pF) for composing the MLCC array, and place these capacitors close to VCC pins. The main power supply from an external application must be a single voltage source. The width of VCC trace should be no less than 2 mm. In principle, a longer VCC trace indicates a wider VCC trace. In addition, in order to get a stable power source, it is recommended to use a zener diode with reverse zener voltage of 5.1 V and dissipation power more than 0.5 W.

Figure 4: Reference Circuit of VCC 3.3.2. 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 can provide sufficient current (at least 2.5 A). If the voltage drop between the input and output is not too high, an LDO is suggested to be used to supply power for the module. If there is a big voltage difference between the input source and the desired output (VCC), a buck converter is preferred to be used as the power supply. The following figure shows a reference design for +5 V input power source. The typical output of the power supply is about 3.7 V and the maximum load current is 3 A.

Figure 20: Recommended Compatible Design of (U)SIM2 Interface In order to enhance the reliability and availability of the (U)SIM card in customers applications, follow the criteria below when designing the (U)SIM circuit:
Keep placement of (U)SIM card connector as close as possible to the module. Keep the trace length as less than 200 mm as possible. Keep (U)SIM card signals away from RF and VCC 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 0.5 mm 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 with parasitic capacitance not exceeding 10 pF. The 22 resistors should be added in series between the module and the (U)SIM card connector so as to suppress EMI spurious transmission and enhance ESD protection. The 33 pF capacitors are used to filter out RF interference. Note that the (U)SIM peripheral circuit should be close to the (U)SIM card connector. The pull-up resistor on USIM_DATA trace 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. NOTE

Figure 21: Reference Circuit of USB 3.0/2.0 Interface AC coupling capacitors C5 and C6 must be placed close to the host and close to each other. C1 and C2 have been integrated inside the module, so do not place these two capacitors on customers schematic and PCB. In order to ensure the signal integrity of USB 2.0 data traces, R1, R2, R3 and R4 components must be placed close to the module, and the stubs must be minimized in PCB layout. In order to ensure that the USB interface designs correspond with USB specifications, comply with the following principles. It is important to route the USB 2.0 & 3.0 signal traces as differential pairs with total grounding. The impedance of USB differential trace is 90 . For USB 2.0 signal traces, the trace lengths must be less than 120 mm, and the differential data pair matching is less than 2 mm (15 ps). For USB 3.0 signal traces, the maximum length of TX and RX differential data pair is recommended to be less than 100 mm, and the TX and RX differential data pair matching is less than 0.7 mm (5 ps). Do not route signal traces under crystals, oscillators, magnetic devices or RF signal traces. It is important to route the USB 2.0 & 3.0 differential traces in inner-layer with ground shielding on not only upper and lower layers but also right and left sides. If USB connector is used, keep the ESD protection components as close as possible to the USB connector. Pay attention to the influence of junction capacitance of ESD protection components on USB 2.0 & 3.0 data traces. Typically, the capacitance value should be less than 2.0 pF for USB 2.0, and less than 0.4 pF for USB 3.0. If possible, reserve four 0 resistors (R1R4) on USB_DP and USB_DM traces, as shown in the above figure.

FULL_CARD_POWER_OFF# could be de-asserted before or after RESET#, 20 ms is a recommended value when it is controlled by GPIO. RESET# is pulled up internally, and it would be de-asserted 50 ms after VCC is powered on. PCIE_CLKREQ_N would be asserted 70 ms after FULL_CARD_POWER_OFF#. PCIE_RST_N should be de-asserted after PCIE_CLKREQ_N. The host must ensure that the reference clock is in the active clock state for at least a period specified by TPCIE_RST_N-CLK, prior to PCIE_RST_N de-assertion. The following principles of PCIe interface design should be complied with so as to meet PCIe V2.1 specifications. It is important to route the PCIe signal traces as differential pairs with total grounding. For PCIe signal traces, the TX and RX differential data pair maximum length is recommended to be less than 250 mm, the TX and RX differential data pair matching are less than 0.7 mm (5 ps). Do not route signal traces under crystals, oscillators, magnetic devices or RF signal traces. It is important to route the PCIe differential traces in inner-layer with ground shielding on not only upper and lower layers but also right and left sides. 3.8.2.

EM120R-GL&EM160R-GL support audio communication via Pulse Code Modulation (PCM) digital interface. The PCM interface supports the following modes:
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 256, 512, 1024 or 2048 kHz PCM_CLK at 8 kHz PCM_SYNC, and also supports 4096 kHz PCM_CLK at 16 kHz PCM_SYNC. In auxiliary mode, the data is 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, PCM interface operates with a 256 kHz PCM_CLK and an 8 kHz, 50% duty cycle PCM_SYNC only. EM120R-GL&EM160R-GL support 16-bit linear data format. The following figures show the primary modes timing relationship with 8 kHz PCM_SYNC and 2048 kHz PCM_CLK, as well as the auxiliary modes timing relationship with 8 kHz PCM_SYNC and 256 kHz PCM_CLK.

So, the control signals (GPIO) of the host device could be a 1.8 V or 3.3 V voltage level and pull-up resistor is not needed on the host side. These two signals are active low, and a reference circuit is shown below. Figure 27: W_DISABLE1# and W_DISABLE2# Reference Circuit 3.10.3.

Characteristics The modules are not protected against electrostatic discharge (ESD) in general. 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 modules. EM120R-GL&EM160R-GL_Hardware_Design 68 / 79 LTE-A Module Series EM120R-GL&EM160R-GL Hardware Design The following table shows the modules electrostatic discharge characteristics.

Thermal Dissipation EM120R-GL&EM160R-GL are designed to work over an extended temperature range. In order to achieve a better performance while working under extended temperatures or extreme conditions (such as with maximum power or data rate, etc.) for a long time, it is strongly recommended to add a thermal pad or other thermally conductive compounds between the module and the main PCB for thermal dissipation. The thermal dissipation area (i.e. the area for adding thermal pad) is shown as below. The dimensions are measured in mm. Figure 38: Thermal Dissipation Area on Bottom Side of Module (Top View) EM120R-GL&EM160R-GL_Hardware_Design 69 / 79 LTE-A Module Series EM120R-GL&EM160R-GL Hardware Design There are some other measures to enhance heat dissipation performance:
Add ground vias as many as possible on PCB. Maximize airflow over/around the module. Place the module away from other heating sources. Module mounting holes must be used to attach (ground) the device to the main PCB ground. It is NOT recommended to apply solder mask on the main PCB where the modules thermal dissipation area is located. Select an appropriate material, thickness and surface for the outer housing (i.e. the mechanical enclosure) of the application device that integrates the module so that it provides good thermal dissipation. Customers may also need active cooling to pull heat away from the module. If possible, add a heatsink on the top of the module. A thermal pad should be used between the heatsink and the module, and the heatsink should be designed with as many fins as possible to increase heat dissipation area. NOTE For more detailed guidelines on thermal design, refer to document [5].
