描述 Description

GENERAL DESCRIPTION
The MSM 7564-01 is a highly integrated single-chip modem IC which provides the functions needed 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 conversion circuit, DTMF generator/detector, programmable tone generator/detector, voice output 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.FEATURES
