73M2901CLIGV

V.22bis Single Chip Modem

TDK Corporation 

®

TDK SEMICONDUCTOR CORP.

DESCRIPTION

The 73M2901CL is a single-chip modem that

combines all the controller (DTE) and data pump

functions necessary to implement an intelligent

V.22bis data modem.

It is adequately suited for embedded applications

where a data return channel is needed through the

telephone network such as Set top Box, Point of

Sale Terminal, Automatic Teller machine, Hand Held

Communication Device and Smart Card Reader.

This device is based on TDK Semiconductor’s

implementation of the industry standard 8032

microcontroller core with a proprietary Multiply/

ACcumulate (MAC) coprocessor; Sigma-Delta A/D

and D/A converters (CODEC); and an analog DAA

drivers. The ROM and RAM necessary to operate

the modem are contained on the device.

Additionally, the 73M2901CL provides an on-chip

oscillator and hybrid.
