TS75C32

The TS75C32 is produced by SGS-THOMSON  microelectronics ,it is a highly integrated modem engine,which can operate in full duplex from 9600 to 300bps.The modem hardware consists of three analog front end(MAFE) chips,three DSP processor chips and additional memory chips plus the V.14 serial output converter.The three SGS-THOMSON analog front end chips(TS68950/1/2) are the transmit interface,the receive interface and the clock generator respectively.The modem signal processing functions are implemented on three ST18930 programmable digital signal processors.

Features of the TS75C32 can be summarized as:(1)CCITT V.32,V.22bis,V.22, V.21, V.23,Bell 212A,Bell 103 compatible modem chip set;(2)CCITT V.29,V.27ter for fax applications;(3)integrated implementation on three DSP and three mafe chips;(4)full duplex operation from 9600 to 300bps;(5)full implementation of the V.32 and V.22bis handshake;(6)V.29/4900bps and V.27ter short train sequences;(7)dynamic range:43dB;(8)two safetllite hops and frequency offset capabilities(10Hz) for the far end echo canceller in V.32 mode;(9)trellis encoding and viterbi decoding;(10)12.5% roll-off raised cosine transmitter pulse shaping;(11)high performance passband fractionally spaced adaptive equalizer;(12)signal quality monitoring;(13)parallel interface to standard microprocessors;(14)serial data transmit capability;(15)V.14 and V.54 implementation;(16)low power mode available(PLCC);(17)bit rate data clocks provided for synchronous data transfer;(18)full diagnostic capability;(19)DTMF generation;(20)call progress tone detection;(21)total power consumption of the TS75C32 below 2W.
