VT-MOD-CELL-B48 Hardware User Manual 5.2.2 Design Guide There is an EMI filtering and ESD protection circuit between SIM card interface and module interface on the user’s board. The SIM support clock frequencies of 3.25MHz. The SIM interface signals consist of four signals that are USIM_PWR, USIM_RST, USIM_CLK, and USIM_DATA (UIM_Vpp isn’t connected also not used in many applications). Due to the relatively low clock frequencies involved, the concern is not the degradation of the SIM signals themselves.
VT-MOD-CELL-B48 Hardware User Manual 5.4 USB Signals VT-MOD-CELL-B48 is compliant with USB 2.0 high speed specification. VT-MOD-CELL-B48 uses USB drive. On the PC one ports can be mapped out, respectively: a. 1 ACM port, carrying AT commands, is mainly used for data traffic; b. 1 CDC-ECM standard card, mainly for service information, the RNDIS interface can be customized. 5.5 Status Indication Signals There are four GPIO pins of VT-MOD-CELL-B48module.
VT-MOD-CELL-B48 Hardware User Manual 5.6 Reset Interface A PERST_N pin provided by VT-MOD-CELL-B48 module can RESET module through an external RESET circuit. Pull low RESET button (RESIN_N pin) to 100 ms, the module will be reset. Figure 4-4 RESET interface Note: 50 ms < t < 200ms. In addition, because the pin is rather sensitive to interference, it is important to pay attention to the module interface board line otherwise it may bring such as interference caused by module reset. 5.
