Reference circuit The reference circuit of USB interface is shown in Figure 2-5 below. 1) To get the reliable USB power supply, it is recommended to use a 10uFC406) filter capacitor and a 22pFC407) filter capacitor which need to be grounded. 2) To reduce the reflection caused by the high frequency alternating signal in the transmission, it is recommended to add a resistor with value below 10 to the DM and DP in USB interface to ensure correct transmission for USB data. Just like the resistors R408 and R409 in Figure 2-5. 3) To avoid static electricity in USB interface, it is recommended to use the ESD protection device. Just like the varistor RV406, RV407 and RV408 with capacitor values below 3pF. 4) To ensure USB working reliably, it is recommended to use additional protection device. Figure 2-5 The reference circuit of USB interface 8 2.2.3. USIM interface DWM-800B supports USIM card in UMTS mode as well as SIM card in GSM/GPRS/EDGE modeand UIM card in WCDMA mode. 2.2.3.1.

Reference circuit The reference circuit of USIM interface is shown in Figure 2-6 below. 1) The DATA line of USIM is connected to SIM power supply by a pull-up resistor with reference value 15K. 2) To avoid the instantaneous voltage overflowing, the resistor with reference value 22 can be used for the DATA, CLK and RST line. Just like the resistors R307, R308 and R309 in Figure 2-6. 3) To avoid the static electricity in USIM socket, it is recommended to use the ESD protection device for the DATA CLK and VCC line. Just like the varistors RV301, RV302, RV303 and RV304 in Figure 2-6 this should be close to the USIM socket as possible. 4) To get more flat USIM power supply, it is recommended to use the filter capacitors. Just like C311 and C312 in Figure 2-6with reference value 33pF and 100nF. 5) To eliminate the peak interference and high frequency interference signal on RST and CLK line, the filter capacities
(C310, C309) can be placed in RST and CLK line, the reference value is 33pF. 9 Figure 2-6 The reference circuit of USIM interface 2.2.4. PCM interface It can just support PCM(Optional).
