73K324L

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

Single-Chip Modem

April 2000

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

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 TDK Semiconductor Corporation's

Pin and software compatible with other

TDK Semiconductor Corporation K-Series family

one-chip modems

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.

Interfaces directly with standard

microprocessors (8048, 80C51 typical)

Serial and parallel microprocessor bus for

control

Selectable asynch/synch with internal

buffer/debuffer and scrambler/descrambler

functions

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.

(continued)

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

and Alternating bit pattern generators

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
