DESCRIPTION

FEATURES

The 73K324BL is a highly integrated single-chip

modem IC which provides the functions needed to

construct a V.22bis compatible modem, capable of

2400 bps full-duplex operation over dial-up lines. The

73K324BL is an enhancement of the 73K324L single-

chip modem, which adds the hybrid hook switch

control, and driver to the 73K324L. The 73K324BL

integrates analog, digital, and switched-capacitor

array functions on a single chip, offering excellent

performance and a high level of functional integration

in a 32-Lead PLCC package.

•

Includes features of 73K324L single-chip

modem

On chip 2-wire/4-wire hybrid driver and off

hook relay buffer

One-chip multi-mode V.22bis/V.22/V.21/V.23

and Bell 212A compatible modem data pump

FSK (300/1200 bps), DPSK (600, 1200 bps), or

QAM (2400 bps) encoding

Software compatible with other Semi-

conductor K-Series one-chip modems

The 73K324BL operates from a single +5 V supply for

low power consumption.

Interfaces directly with standard micro-

processors (80C51 typical)

The 73K324BL is designed to appear to the systems

designer as a microprocessor peripheral, and will

easily interface with popular single-chip micro-

processors (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 simplifies address demultiplexing. Data

communications normally occur through a separate

serial port.
