73K324L

CCITT V.22bis,V.23,V.22,V.21,Bell 212A

Single-Chip Modem

DATA SHEET

JULY 2005

DESCRIPTION

The 73K324L is a highly integrated single-chip

modem IC, which provides the functions, needed to

design a Quad-mode CCITT and Bell 212A

compatible modem capable of operation over dial-up

lines. The 73K324L adds V.23 capability to the

CCITT modes of TERIDIAN Semiconductor

Corporation's 73K224 one-chip modem, allowing a

one-chip implementation in designs intended for

European markets, which require this added

Modulation mode. The 73K324L offers excellent

performance and a high level of functional

integration in a single IC. The device supports

V.22bis, V.22, Bell 212A, V.21, and V.23 operating

modes,

allowing

both

synchronous

and

asynchronous operation as defined by the

appropriate standard.

The 73K324L is designed to appear to the Systems

Engineer as a microprocessor peripheral, and will

easily

interface

with

popular

one-chip

microcontrollers (80C51 typical) for control of

modem functions through its 8-bit multiplexed

address/data bus. A serial control bus is available

for applications not requiring a parallel interface. An

optional package with only the serial control bus is

also available. Data communications occurs through

a separate serial port.
