MG3732 module 17This chapter introduces each logic function interfaces of MG3732 module & its operation descriptions, and provides the designing sample.  Power and Reset Interface  COM Port  UIM Card Interface  Audio Interface  PCM interface  USB2.0 interface  Antenna Interface Remarks: In the system, the module layout should be far away from high-speed circuit, switch power, power transformer, large power inductor, or single chip microcomputer’s clock circuit. 4.2 Power and Reset 4.2.1 Power Design The module could work under two power modes: 1. Power adaptor; 2. Battery The power could directly be supplied externally, the external power is added directly to V_MAIN and meets the voltage requirements in table 4-1. The external power could be supplied by the power adaptor with constant output, battery, USB power converter, etc. It’s recommended to design 2A current to meet the requirements of GSM/GPRS. Table 4-1 Voltage characteristics Classification MIN. Typical Max. Input voltage 3.3 V 3.8 V 4.25 V  Power on The module will be turned off after power-on normally. To turn on the module, provide a 2000-2500mS low level pulse to ON/OFF PIN.  Power off To turn off the module, provide a 2500-4000mS low level pulse to ON/OFF PIN.  Reset To reset the module, provide a 2500-4000mS low level pulse to ON/OFF PIN After reset, the module will be turned off. To turn on the module, provide a 2000-2500mS low level pulse to ON/OFF PIN.  V_MSME_1V8 There is a voltage output pin with current adjuster on MG3732 module, which can be used to supply external power to the board. The voltage of this pin and the voltage of baseband processor/memory come from the same voltage adjuster. The voltage output is available only when the module is on. The normal output voltage is 1.8V, and the user should absorb the current from this pin as little as possible (less than 10mA). Generally, it is recommended to use this pin for pull-up when matching the level.
MG3732 module 18  Other Advice In order to make sure the data is saved safely, please don’t cut off the power when the module is on. It’s strongly recommended to use ON/OFF pin or AT command to turn off the mobile phone. 4.3 COM Port The module provides a full duplex UART interface, whose maximal data rate is 230.4kbps and typical data rate is 11.5kbps. External interface is 1.8VCMOS level signal, which could be used for upgrade, port communication, etc. When using MG3732 module’s UART port to communicate with PC or MCU, please pay attention to the direction of TX, RX. It’s specially noted that MG3732 module’s UART port only supports 1.8V, therefore for non 1.8V external UART, it needs to convert the level. Normally a dynatron is used to realize the level conversion. As shown in figure 4-1, the resistance is just for your information, please calculate again during the design. Figure 4-1 UART Interface Reference Design Diagram 4.4 UIM Card Interface
MG3732 module 19The module supports 2.85V/1.8V UIM card, and it’s strongly recommended to add ESD component to protect UIM card as shown in figure 4-2. Figure 4-2 UIM Card Circuit Reference Design Diagram Note: The clock data rate of UIM card circuit is 4M, and the card socket should be laid closely around the module and the wiring should be as short and thick as possible. 4.5 Audio Interface The module provides 2 speaker interfaces and 2 microphone interfaces. Only one pair I/O works at the same time. See the audio interface circuit in figure 4-3. Figure 4-3 Audio Interface Circuit Reference Design Diagram  Microphone The two microphone interfaces MIC_N and MIC_P are differential interface, which could also be used for single end input. It’s recommended to use differential mode to reduce the noises and it is directly connected with
MG3732 module 20the receiver. MIC_P is single ended interface, which could be directly connected to the microphone since the offset voltage is internally provided.  Earpiece The earpiece interface EAR1_P and EAR1_N are both differential interfaces with 32Ω resistance; EAR2_P is single-ended interface with 32Ω resistance and no coupling of capacitor is required.  Design of audio interface on the receiver Select the microphone with the sensitivity lower than -52dB since EAR1’s output power is 35mW and the max. gain inside MIC1 reaches 52dB. Note: if other kind of audio input method is adopted, the input signal should be within 1V. If the signal voltage is lower than 1V, then the pre-amplifier should be added. If the signal voltage is higher than 1V, then network attenuation should be added  Design of audio interface on the earpiece Select the microphone with the sensitivity lower than -52dB since EAR2’s output power is 10.8mW and the max. gain inside MIC2 reaches 52dB. The level of MIC2_P PIN is about 1.8V. The receiver’s design is just the same as the receiver’s. 4.6 PCM Interface The module’s PCM interface provides PCM_CLK, PCM_SYNC, PCM_DIN, PCM_DOUT，and it supports 2.048MHz PCM clock data rate and 8K frame data rate. PCM clock will stop the output when it enters the dormant mode. The module’s PCM interface must work under Master mode, and the clock and SYNC signal must be sent by the module. The device connected with the interface can word under Slave mode only. See the time sequence of PCM interface in figure 4-4.
MG3732 module 21Figure 4-4 Time Sequence of PCM Interface 4.7 USB2.0 Interface The module provides USB2.0 HS interface with 480Mbps, which is composed of VBUS, D+ and D-. You can directly connect USB signal interface when designing the module’s external circuit, but try to add ESD
MG3732 module 22protector during the design to avoid damaging the module. D1 is USB2.0 ESD protector in the figure, and the Junction capacitance is small than 3P. VBUS is connected to the external host VBUS. The USB operating voltage is: 4.75—5.25V with the typical value of 5V. See figure 4-5. Figure 4-5 USB Interface Circuit Reference Design Diagram 4.8 Antenna Interface Proper measures should be taken to reduce the access loss of effective bands, and good shielding should be established between the external antenna and the RF connector. Besides, the external RF cables should be kept far away from all interference sources such as high-speed digital signal or switch power supply. According to mobile station standard, stationary wave ratio of antenna should be between1.1 to 1.5, and input impedance is 50 ohm. Different environments may have different requirements on the antenna’s gain. Generally, the larger gain in the band and smaller outside the band, the better performance the antenna has. Isolation degree among ports must more than 30dB when multi-ports antenna is used. For example, between two different polarized ports on dual-polarized antenna, two different frequency ports on dual-frequency antenna, or among four ports on dual-polarized dual-frequency antenna, isolation degree should be more than 30dB.

MG3732 module 245.2 Module Assembly Diagram See the assembly diagram of MG3732 module in figure 5-2. Figure 5-2 Module’s Assembly Diagram Note: it’s recommended to open a window in the relevant position of the red area on the bottom layer for the convenience of maintenance. The red box is made manually and doesn’t exist on the actual object. See the dimensions for the hole in the figure above.
MG3732 module 25 5.3 Module’s Fixing Method The module’s fastening method adopts direct manual soldering to avoid second-time soldering. It’s strongly recommend to use the manual soldering because MC3732 module board is just 0.8mm thick and QSC6270 BGA space is too small. The second-time soldering would cause the melting of soldering tin and lead to short circuit of QSC6270 main chip, such as USB disconnected, large current, etc. FCC Regulations: This device complies with part 15 of the FCC Rules.
