CMOS LSI
LC89201
9600-bps Facsimile Modem
Preliminary
Overview
The LC89201 is a CMOS single-chip, synchronous, half-
duplex, 9600-bps fax modem designed for use with public
telephone networks. Built in are such essential features for
Group III facsimile systems as modulator, demodulator,
transmission filters, and V.24 interface.
The LSI supports the V.29, V.27ter, V.21ch2, T.30, and
T.4 telecommunications standards promulgated by the
ITU-T (formerly the CCITT) for transmission at 9600,
7200, 4800, 2400 and 300 bps. Advanced signal
processing provides reliable data transmissions even under
adverse circuit conditions. Built-in High-level Data Link
Control (HDLC) support permits the construction of Error
Correction Mode (ECM) facsimile machines.
