DESCRIPTION

FEATURES

•

One-chip multi-mode V.22bis/V.22/V.21 and Bell

212A/103 compatible modem data pump

FSK (300 bit/s), DPSK (600, 1200 bit/s), or QAM

(2400 bit/s) encoding

The 73K224L is a highly integrated single-chip

modem IC which provides the functions needed to

construct a V.22bis compatible modem, capable of

2400 bit/s full-duplex operation over dial-up lines. The

73K224L offers excellent performance and a high

level of functional integration in a single 28-pin DIP

package. This device supports V.22bis, V.22, V.21,

Bell 212A and Bell 103 modes of operation, allowing

both synchronous and asynchronous communication.

The 73K224L is designed to appear to the systems

designer as a microprocessor peripheral, and will

Selectable

with

internal

microprocessors (80C51 typical) for control of modem

functions through its 8-bit multiplexed address/data

bus or via an optional serial control bus. An ALE

control line simplifies address demultiplexing. Data

communications normally occur through a separate

serial port. The 73K224L is pin and software

compatible with the 73K212L and 73K222L single-

chip modem ICs, allowing system upgrades with a

single component change.

buffer/debuffer

and scrambler/descrambler

•

All synchronous and asynchronous operating

modes (internal, external, slave)

Adaptive equalization for optimum performance

over all lines

Programmable transmit attenuation (16 dB, 1 dB

steps), selectable receive boost (+18 dB)

Call progress, carrier, answer tone, unscrambled

mark, S1, and signal quality monitors

DTMF, answer and guard tone generators

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

Alternating bit, S1 pattern

CMOS technology for low power consumption

(typically 100 mW @ 5V) with power-down mode

(15 mW @ 5V)

The 73K224L operates from a single +5V supply for

low power consumption.
