The nominal frequency for this clock is 44MHz. This is used internally to generate divide by 2 and 4 for the transceiver clock Baseband Processor Receiver Port Pins PIN NAME PIN I/O TYPE DESCRIPTION RX_IF_AGC O Analog drive to the IF AGC control RX_RF_AGC O Drive to the RF AGC stage attenuator. CMOS digital RX_IF_DET I Analog input to the receive power A/D converter for AGC control RXI, ± I Analog input to the internal 6-bit A/D of the In-phase received data. Balanced differential 10+/11- RXQ, ± I Analog input to the internal 6-bit A/D of the Quadrature received data. Balanced differential 13+/14- Baseband Processor Transmitter Port Pins PIN NAME PIN I/O TYPE DESCRIPTION TX_AGC_IN I Input to the transmit power A/D converter for transmit AGC control TX_IF_AGC O Analog drive to the transmit IF power control TXI ± O TX Spread baseband I digital output data. Data is output at the chip rate. Balanced differential 23+/24- TXQ ± O TX Spread baseband Q digital output data. Data is output at the chip rate. Balanced differential 29+/30- ISL3873A |
