V.22, V.21, Bell 212A, Bell 103 Single-Chip
Modem with Integrated Hybrid
June 2001
DESCRIPTION
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
functions on a single substrate, offering excellent
performance and a high level of functional
integration in a 32-Lead PLCC package. It operates
from a single +5 V supply.
array
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
included for self-testing.
