Preliminary

Overview

The LC8920 is designed for synchronous, half-duplex,

9,600 bps CMOS single chip modem applications using

public telephone networks. This LSI has built-in

modulation-demodulation components meeting modem

requirements, along with transmitter-receiver filters and

V.24 interfacing. In addition, construction of Group 3

and Group 2 facsimile systems has been simplified.

The LC8920 conforms to V.29, V.27ter, T.30, T.4 and

T.3 recommendations for telecommunications as set

forth by CCITT (CCITT: International Telephone and

Telegraph Consultative Committee). Transfer speeds

supported by this LSI include 300, 2400, 4800, 7200 and

9600 bps rates. Advanced signal processing functions

permit data transmission and reception even under poor

line conditions.
