73K222BL  
V.22, V.21, Bell 212A, Bell 103 Single-Chip  
Modem with Integrated Hybrid  
April 2000  
DESCRIPTION  
FEATURES  
The 73K222BL is a highly integrated single-chip  
modem IC which provides the functions needed to  
construct a CCITT V.22, V.21, Bell 212A and Bell  
103, compatible modem, capable of 1200 bit/s full-  
duplex operation over dial-up lines. The 73K222BL  
is an enhancement of the 73K222AL single-chip  
modem which adds the hybrid hook switch control,  
and driver to the 73K222AL. In Bell 212A mode, the  
73K222BL provides the normal Bell 212A and Bell  
103 functions and employs a 2225 Hz answer tone.  
The 73K222BL 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 device integrates  
analog, digital, and switched-capacitor array  
functions on a single substrate, offering excellent

Full-duplex operation at 0-300 bit/s (FSK) or  
600 and 1200 bit/s (DPSK)  
On chip 2-wire/4-wire hybrid driver and off-

with  
standard  
microcontroller (8048, 80C51 typical)  
Serial port for data transfer  
Both synchronous and asynchronous modes  
of operation including V.22 extended  
overspeed  
performance and  
a
high level of functional  
integration in a 32-Lead PLCC and 44-Lead TQFP  
package. It operates from a single +5 V supply.  
Call progress, carrier, precise answer tone  
(2100 or 2225 Hz), and long loop detectors  
The 73K222BL includes the DPSK and FSK  
modulator/demodulator functions, call progress and  
handshake tone monitor and a tone generator  
capable of tones required for European applications.  
This device supports V.22 (except mode v) and V. 21  
modes of operation, allowing both synchronous and  
asynchronous communication. Test features such as  
analog loop, digital loop, and remote digital loopback  
are supported. Internal pattern generators are also  
DTMF, and 550 or 1800 Hz guard tone  
generators  
Test modes available: ALB, DL, RDL, Mark,  
Space, Alternating bit patterns  
Precise automatic gain control allows 45 dB  
dynamic range  
CMOS technology for low power consumption  
using 60 mW @ 5 V  
included for self-testing.
