| Ordering number : EN*4974 CMOS LSI LC89201 9600-bps Facsimile Modem Preliminary 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. 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. * * * * * * * 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). Package Dimensions unit: mm 3174-QFP80E [LC89201] 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 x 8 bits, with built-in FIFO) * Programmable interrupt generator.
