73K222AL  
V.22, V.21, Bell 212A, 103  
Single-Chip Modem  
April 2000  
DESCRIPTION  
FEATURES  
The 73K222AL is a highly integrated single-chip  
modem IC which provides the functions needed to  
·

·
One-chip CCITT V.22, V.21, Bell 212A and Bell  
103 standard compatible modem data pump  
construct  
a
CCITT V.22, V.21 and Bell 212A  
Full-duplex operation at 0-300 bit/s (FSK) or 600  
and 1200 bit/s (DPSK)  
compatible modem, capable of 1200 bit/s full-duplex  
operation over dial-up lines. The 73K222AL is an  
enhancement of the 73K212L/AL single-chip modem  
which adds V.22 and V.21 modes to the Bell 212A and  
103 operation of the 73K212AL. In Bell 212A mode,  
the 73K222AL provides the normal Bell 212A and 103  
functions and employs a 2225 Hz answer tone. The  
73K222AL in V.22 mode produces either 550 or 1800  
Hz guard tone, recognizes and generates a 2100 Hz  
answer tone, and allows 600 bit/s V.22 or 0-300 bit/s  
V.21 operation. The 73K222AL integrates analog,  
digital, and switched-capacitor array functions on a  
single substrate, offering excellent performance and a  
high level of functional integration in a single 28-pin  
DIP, PLCC and 44-pin TQFP configuration. The  
73K222AL operates from a single +5V supply. The  
73K222AL is a new version replacing the 73K222L.  
The 73K222AL should be specified for all new  
designs.
