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.
