MG3732 module This 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.
MG3732 module 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.
MG3732 module The 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.
MG3732 module the 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.
MG3732 module Figure 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-.
MG3732 module protector 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.
MG3732 module 5 Mechanical Design 5.1 Appearance Diagram See the appearance of MG3732 module in figure 5-1. Figure 5-1 MG3732 Module’s Appearance Dimensions:（LxWxH）：39.5 mm x 31.0mm x2.
MG3732 module 5.2 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 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.
MG3732 module all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. Maximum antenna gain allowed for use with this device is 2 dBi. When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re-moved.
