73K221AL  
CCITT V.22, V.21  
Single-Chip Modem  
January 1999  
DESCRIPTION  
FEATURES  
The 73K221AL is a highly integrated single-chip  
modem IC which provides the functions needed to  
construct a CCITT V.22 and V.21 compatible  
modem, capable of 1200 or 0-300 bit/s full-duplex  
operation over dial-up lines. The 73K221AL is an  
enhancement of the 73K212L single-chip modem  
with performance characteristics suitable for  
European and Asian telephone systems. The  
73K221AL produces either 550 or 1800 Hz guard  
tone, recognizes and generates a 2100 Hz answer  
tone, and allows V.21 for 300 Hz FSK operation.  
The 73K221AL 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  
or PLCC package.  
One-chip CCITT V.22 and V.21 standard  
compatible modem data pump  
Full-duplex operation at 0-300 bit/s (FSK) or  
600 and 1200 bit/s (DPSK)  
Pin and software compatible with other  
TDK Semiconductor Corporation K-Series  
1-chip modems  
Interfaces directly with standard micro-  
controllers (8048, 80C51 typical)  
Serial port for data transfer  
Both Synchronous and Asynchronous modes  
of operation  
Call progress, carrier, precise answer tone  
(2100 Hz), and long loop detectors  
DTMF, and 550 or 1800 Hz guard tone  
generators  
The 73K221AL includes the DPSK and FSK  
modulator/demodulator functions, call progress and  
handshake tone monitor test modes, and a tone  
generator capable of producing DTMF, answer and  
550 or 1800 Hz guard tone. This device supports  
V.22 (except mode v) and V. 21 modes of operation,  
allowing both synchronous and asynchronous  
communications. The 73K221AL is designed to  
appear to the systems designer as a microprocessor  
peripheral, and will easily interface with popular one-  
Test modes available: ALB, DL, RDL, Mark,  
Space, Alternating bit patterns  
Precise automatic gain control allows 45 dB  
dynamic range  
Space efficient 28-pin DIP or 28-Pin PLCC  
packages  
CMOS technology for low power consumption  
using 60 mW @ 5V  
Single +5 volt supply
