73K224L  
V.22bis/V.22/V.21/ Bell 212A/Bell 103  
Single-Chip Modem  
April 2000  
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  
and 44-pin TQFP package. This device supports  
V.22bis, V.22, V.21, Bell 212A and Bell 103 modes of  
Pin and software compatible with other TDK

operation,  
allowing  
both  
synchronous  
and  
asynchronous communication. The 73K224L is  
designed to appear to the systems designer as a  
microprocessor peripheral, and will easily interface  
with popular single-chip 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  
Selectable  
buffer/debuffer  
functions  
asynch/synch  
with  
internal  
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  
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.  
The 73K224L operates from a single +5V supply for  
low power consumption.  
CMOS technology for low power consumption  
(typically 100 mW @ 5V) with power-down mode  
(15 mW @ 5V)  
The 73K224L is ideal for use in either free-standing or  
integral system modem products where full-duplex  
(continued)  
TTL and CMOS compatible inputs and outputs
