73M2901CL
V.22bis Single Chip Modem

May 2002
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.
