TS75320

The TS75320 is a high performance voiceband data modem echo canceller implemented no a single chip using advanced digital signal processing technology.Using sophisticated adaptive algorithms,the TS75320 realizes the high precision cancellation of near-end and far-end echoes,even in the presence of frequency offset in the far end echo.The residual cancellation levels and converhence rates of the TS75320 meet or exceed the demanding requirements of high performance V.32 modems.The TS75320 is ideally suited for high performance low-cost integrated V.32 solutions.

Here are the features of TS75320:(1)simplified interface circuitry for flexible adaption to a wide range of V.32 configurations;(2)dovetailed hardware and firmware connection with TS68950/1/2 modem analog front-end chip set;(3)key component in the advanced TS7532 V.32 modem;(4)16 msec of echo path impulse response in the near end and in the far-end cancellers;(5)1.14 sec of channel delay(two satellite hops) in far-end echo canceller;(6)10 Hz of frequency offset in far-end echo path;(7)meets or exceeds the requirements of CCITT recommendation V.32.

The absolute maximum ratings of the TS75320 can be summarized as:(1)supply voltage:-0.3 to 7.0 V;(2)input voltage:-0.3 to 7.0 V;(3)operating temperature range:0 to 70 and (4)storage temperature range:-55 to 150.If you want to know more information about it,please download the datasheet in www.chinaicmart.com or www.seekic.com
