Motorola announces a multi-protocol, multi-band digital transceiver IC that combines the major building blocks required for next-generation multiple purpose, multi-band wireless products. Called the MC13760, the software-programmable IC functions over a wide range of input frequencies in multi-band, multi-mode, GSM/DCS/TDMA/AMPS cellular phones, including GPRS. It also has potential for use in personal digital assistants (PDAs), satellite phones, iDEN, and TETRA radios. The MC13760 features fractional-N synthesizers, a reconfigurable zero IF receiver with programmable bandwidth, receive A/D conversion, multi-rate data interface to the baseband DSP, direct launch digital modulator, and full transmit support circuits. The device operates at 2.75 V and provides a "deep sleep" mode with drain current as low as 50 æA. General purpose support circuits, such as D/A and A/D converters, battery save and tri-state control switches, are also included on the IC.
