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 Ter mina l, Autom atic T eller mach ine, H and 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.
