DESCRIPTION

FEATURES

The 73K324L is a highly integrated single-chip

modem IC, which provides the functions, needed to

•

One chip Multi-mode CCITT V.22bis, V.22, V.21,

V.23 and Bell 212A compatible modem data pump

design

a Quad-mode CCITT and Bell 212A

FSK (75, 300, 1200 bit/s), DPSK (600, 1200 bit/s),

or QAM (2400 bit/s) encoding

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

Pin and software compatible with other

TERIDIAN Semiconductor Corporation K-Series

family one-chip modems

•

Interfaces directly with standard

microprocessors (8048, 80C51 typical)

performance and

high level of functional

Serial and parallel microprocessor bus for

control

integration in a single IC. The device supports

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

Selectable asynch/synch with internal

buffer/debuffer and scrambler/descrambler

functions

modes,

allowing

both

synchronous

and

asynchronous operation as defined by the

appropriate standard.

•

All synchronous (internal, external, slave) and

Asynchronous Operating modes

The 73K324L is designed to appear to the Systems

Engineer as a microprocessor peripheral, and will

Adaptive equalization for optimum performance

over all lines

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

Programmable transmit attenuation (16 dB, 1 dB

steps), and selectable receive boost (+18 dB)

Call progress, carrier, answer tone, unscrambled

mark, S1, and signal quality monitors

DTMF, answer, calling, SCT and guard tone

generators

a separate serial port.

Test modes available: ALB, DL, RDL; Mark, Space

and Alternating bit pattern generators

(continued)

CMOS technology for low power consumption

(100 MW @ 5 V) with power-down mode

(15 mW @ 5V)

•

4-wire full duplex operation in all modes
