GSM/DCS/TDMA/AMPS Multi-Protocol Transceiver

The MC13760 Multi–Protocol, Multi–Band Digital Transceiver IC combines, on a single Advanced BiCMOS chip, the major building blocks required for next generation multi–purpose, multi–band wireless products. The device includes the majority of the circuitry necessary for IF signal processing between the RF front end and the DSP and backend. The MC13760 contains two fractional–N synthesizers, a re–configurable zero IF receiver with programmable bandwidth, receive A/D conversion, multi–rate data interface to the baseband DSP, direct launch digital modulator, full transmit support circuits, and general purpose support circuits such as D/A and A/D converters, battery save and tri–state control switches
