Baseband analog processing IC for dual-mode CDMA/FM cellular phone

For the availability of this product, please contact the sales office.

Description

80 pin LQFP (Plastic)

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
