Overview

The LC89201 is a CMOS single-chip, synchronous, halfduplex, 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.

Features

? Support for the following ITU-T standards: V.29 (9600, 7200 and 4800 bps), V.27ter (4800 and 2400 bps), V.21ch2 (300 bps), T.30, and T.4.

? Half-duplex operation.

? Group III facsimile support.

? Automatic switching between high- (V.29 and V.27ter) and low-speed (V.21ch2) incoming facsimiles.

? Short training (for ITU-T V.27ter only).

? HDLC framing and deframing (V.29, V.27ter, and V.21ch2).

? Tone generation and detection.

? Dual-tone multifrequency (DTMF) generation and detection.

? Call progress tone detection.

? Pseudo link back tone generation.

? Built-in automatic adaptive equalizer.

? Built-in fixed-amplitude amplifier.

— Link amplitude equalizer

— Cable amplitude equalizer

? Built-in transmission filters (digital filters).

? Programmable transmission level adjustment.

? Dynamic range for reception of 0 to –47 dBm.

? Programmable reception sensitivity adjustment.

? DTE interface.

— Serial interface (ITU-T V.24)

— Parallel interface (4 words × 8 bits, with built-in FIFO)

? Programmable interrupt generator.

? Built-in eye pattern generator.

? Adaptive differential pulse-code modulation (ADPCM).

? Caller ID detection.

? Built-in diagnostics.

? Energy-saving CMOS design (typ. 250 mW).

? Single 5 V power supply.

? 80-pin flat package (QIP-80E).
