Voltage Input Low 4.5 VIL -0.3 1.01045 Volts Output Power The phone output power is measured at the end of phone module antenna connector using the RF power meter. The power level of the phone module is controlled by the base station and the range of the power level is varied from Min output power to Max output power that is defined in the table below. Item Specification Max Output Power Power Class II Min Output Power 4.6 Audio Interface 4.6.1 PCM Audio 4.6.1.1 MSM Timing Parameters 4.6.1.
4.6.1.3 MSM Receive Timing 4.6.1.4 MSM Transmitting Timing 4.6.2 UART Data Interface The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that conforms to RS-232 interface protocol. The UART can be used as a serial data port in Mobile Station testing and debugging with a properly written, user-defined download program. All communication between the microprocessor and the UART goes through the microprocessor interface.
The UART has a 512-byte transmit FIFO and a 512-byte receive FIFO. UART1 (CAIT_RX, CAIT_TX) UART2 (UART_RX, UART_TX) Mobile Station Test, Debugging, Download Communication between the Phone Module and TCU The phone shall have the following UART parameters set by default. Baud = 9600 Data Bits = 8 Parity = ODD Stop Bit = 1 Start Bit = 1 Flow Control = None Line feed and Carriage return shall be sent following each command and response.
4.6.3 Cellular Antenna Open/Short Sense The phone module provides the antenna diagnostics function by the antenna detection circuit. The antenna detection circuit can detect three statuses: GOOD, OPEN and SHORTED. The detection circuit can support the antenna resistance values of 1 kOhm to 20 kOhm. The commands are detailed in the AT command manual. DC Voltage Status GOOD OPEN SHORTED 2.60V ADC Voltage 1.30V 2.60V 0.
