Multi-Protocol Transceiver
MC13760
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.
Intended for use in a combined GSM/TDMA/AMPS/iDEN portable
wireless phone product in the 800/900/1800/1900 MHz bands. The
MC13760 can be used over a wide range of RF and IF frequencies. The
main PLL prescaler input is usable to over 2.0 GHz and the IF quadrature
downconverter operates up to 400 MHz.
The MC13760 has separate receive IF inputs and a common zero–IF IQ
receiver for TDMA and for GSM accommodating the receiver architectural
need to use different IF frequencies and filters without the need for additional
switches.
