73K224BL  
V.22bis, V.22, V.21, Bell 212A, 103  
Single-Chip Modem w/ Integrated  
Hybrid  
Simplifying System Integration™  
DATA SHEET  
DESCRIPTION  
FEATURES  
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 package.  
Includes features of 73K224L single-chip  
modem  
On chip 2-wire/4-wire hybrid driver and off  
hook relay buffer driver  
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  
Software compatible with other TERIDIAN  
Semiconductor K-Series one-chip modems  
The 73K224BL operates from a single +5 V supply for  
low power consumption.  
Interfaces directly with standard micro-  
processors (80C51 typical)  
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.  
Parallel or serial bus for control  
Selectable  
internal  
buffer/debuffer  
and  
scrambler/descrambler functions  
All asynchronous and synchronous operating  
modes (internal, external, slave)
