Decrease Voltage Drop The power supply range of the module is 3.3V~ 4.3V. Make sure the input voltage will never drop below 3.3V. If the voltage drops below 3.3V, the module will turn off automatically. The following figure shows the voltage drop during transmitting burst in 2G network, the voltage drop will be less in 3G network. < 400mVCurrentVBAT≤ 2.0Aburst burstMin. 3.3V Figure 6: Voltage Drop during Transmitting Burst To decrease voltage drop, a bypass capacitor of about 100µF with low ESR should be used. Multi-layer ceramic chip (MLCC) capacitor can provide the best combination of low ESR. The main power supply from an external application has to be a single voltage source and splits into 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, and the principle of the VBAT trace is the longer, the wider. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the VBAT pins. The capacitors should be placed close to the UG96’s VBAT pins. In addition, in order to get a stable power source, it is suggested that you should use a zener diode of which reverse zener voltage is 5.1V and dissipation power is more than 0.5W. The following figure shows star structure of the power supply.

Reference Design for Power Supply The power design for the module is very important, since the performance of power supply for the module largely depends on the power source. The power supply is capable of providing the sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested that a LDO should be used to supply power for 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 a power supply. The following figure shows a reference design for +5V input power source. The designed output for the power supply is about 3.8V and the maximum load current is 3A.

After logging off, module sends out “OK”, and then sends out “POWERED DOWN” and shuts down the internal power supply. The power on VBAT pins is not allowed to be turned off before the URC “POWERED DOWN” is output to avoid data loss. If logging off is not done within 40s, module will shut down internal power supply forcibly. After that moment, the module enters the power down mode, no other AT commands can be executed, only the RTC is still active.

RTC Interface The RTC (Real Time Clock) can be powered by an external capacitor through the pin VRTC when the module is powered down and there is no power supply for the VBAT. If the voltage supply at VBAT is disconnected, the RTC can be powered by the capacitor. The capacitance determines the duration of buffering when no voltage is applied to UG96. The capacitor is charged from the internal LDO of UG96 when there is power supply for the VBAT. A serial 1KΩ resistor has been placed on the application inside the module. It limits the input current of the capacitor. The following figure shows the reference circuit for VRTC backup. Large Capacitance CapacitorModuleRTC Core1KVRTCC Figure 19: RTC Supply from Capacitor In order to evaluate the capacitance of capacitor according to the backup time, you have to consider the following parameters:  VRTC - The starting voltage of the capacitor. (Volt)  VRTCMIN - The minimum voltage acceptable for the RTC circuit.(Volt)  I - The current consumption of the RTC circuitry when VBAT = 0.(Ampere)  B Time - Backup Time.(Second)  C - The backup capacitance. (Farad) When the power is off and only VRTC is running, the way of calculating the backup capacitor as follows: C= B Time *I/ (VRTC-VRTCMIN) For example, when the capacitor is 1000uF:  VRTC=1.8V  VRTCMIN=1.0V  I=2uA  C=1000uF The backup time is about 400s.

Assure the length of the trace is as less than 200mm as possible.  Keep USIM card signal away from RF and VBAT alignment.  Assure the ground between module and USIM holder short and wide. Keep the width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential. The decouple capacitor of USIM_VDD should be less than 1uF and must be near to USIM holder.  To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away with each other and shield them with surrounded ground.  In order to offer good ESD protection, it is recommended to add TVS such as WILL (http://www.willsemi.com). The 22Ω resistors should be added in series between the module and the USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the USIM peripheral circuit should be close to the USIM holder.  The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion is applied, and should be placed close to the USIM holder. 3.12. USB Interface UG96 contains one integrated Universal Serial Bus (USB) transceiver which complies with the USB 1.1/2.0 specification and supports high speed (480Mbps) and full speed (12Mbps) mode.

UMTS/HSPA Module Series UG96 Hardware Design UG96_Hardware_Design Confidential / Released 75 / 75 10 Appendix C GPRS Multi-slot Class Twenty-nine classes of GPRS multi-slot modes are defined for MS in GPRS specification. Multi-slot classes are product dependant, and determine the maximum achievable data rates in both the uplink and downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots, while the second number indicates the amount of uplink timeslots. The active slots determine the total number of slots the GPRS device can use simultaneously for both uplink and downlink communications. The description of different multi-slot classes is shown in the following table. Table 32: GPRS Multi-slot Classes Multislot Class Downlink Slots Uplink Slots Active Slots 1 1 1 2 2 2 1 3 3 2 2 3 4 3 1 4 5 2 2 4 6 3 2 4 7 3 3 4 8 4 1 5 9 3 2 5 10 4 2 5 11 4 3 5 12 4 4 5
