MSM7564-01

A Single Chip 14.4 kbps Data & Fax Modem

GENERAL DESCRIPTION

TheMSM7564-01isahighlyintegratedsingle-chipmodemICwhichprovidesthefunctionsneeded

to construct 14.4 kbps full-duplex and half-duplex modems. This device is compliant with the

following data communication formats : ITU-T Recommendation V.32bis, V.32, V.22bis, V.21 and

Bell standard Bell 212A and Bell103 modes, and facsimile communication formats : ITU-T

Recommendation V.17, V29, V.27ter, V.21 ch2.

This device contains fundamental functions : high speed DSP, analog front end, and digital logic

circuit. It also provides additional circuits such as test functions, synchronous-asynchronous

conversioncircuit,DTMFgenerator/detector,programmabletonegenerator/detector,voiceoutput

function and sleep mode. The MSM7564-01 is designed to provide a microprocessor peripheral to

interface with popular single-chip microprocessors for the control of modem functions through its

8-bit multiplexed address/data bus.
