73K324BL
V.22bis/V.22/V.21/V.23 Bell 212A
Single-Chip Modem w/Integrated Hybrid
DESCRIPTION
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 and 44-Lead TQFP package.
The 73K324BL operates from a single +5 V supply for
low power consumption.
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.
