CS61880集成電路（IC）的電信規(guī)格書PDF中文資料

CS61880屬于集成電路（IC）的電信。由凌云邏輯制造生產(chǎn)的CS61880電信電信接口集成電路 (IC) 為通信網(wǎng)絡接口提供特定功能和控制，例如以太網(wǎng)切換、線路驅(qū)動器、ISDN、放大器、通道擴展器、數(shù)字鎖相環(huán)、DTMF、音頻發(fā)生器和解碼器、回聲消除、檢測器和發(fā)生器、DDA、電話線路監(jiān)控器和主叫號碼標識。

Description

The CS61880 is a full-featured Octal E1 short-haul LIU that supports 2.048 Mbps data transmission for both E1 75 ? and E1 120 ? applications. Each channel provides crystal-less jitter attenuation that complies with the most stringent standards. Each channel also provides internal AMI/HDB3 encoding/decoding. To support enhanced system diagnostics, channel zero can be configured for G.772 non-intrusive monitoring of any of the other 7 channels’ receive or transmit paths.
