73K224BL
V.22bis/V.22/V.21/Bell 212A/103
Single-Chip Modem w/ Integrated Hybrid
April 2000
DESCRIPTION
The 73K224BL 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 73K224BL is an enhancement of the 73K224L
single-chip modem which adds the hybrid hook
switch control, and driver to the 73K224L. The
73K224BL 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 73K224BL operates from a single +5 V supply
for low power consumption.
The 73K224BL 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.
