Description

The CXA3003R is a baseband analog processing IC for dual-mode CDMA/FM cellular phone. The CXA3003R interfaces between the inter-frequency section and the digital processing circuitry of the telephone. The receive circuit functions primarily convert analog IF signals to the analog baseband frequency range and to convert the analog baseband signals into digital signals. Transmit circuits convert digital data into analog baseband signals CXA3003R which are then up-convert to the IF frequency range.
