CS61884集成電路（IC）的電信規(guī)格書PDF中文資料

CS61884屬于集成電路（IC）的電信。由凌云邏輯制造生產(chǎn)的CS61884電信電信接口集成電路 (IC) 為通信網(wǎng)絡(luò)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(kuò)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(biāo)識。

Description

The CS61884 is a full-featured octal E1/T1/J1 short-haul LIU that supports both 1.544 Mbps or 2.048 Mbps data transmission. Each channel provides crystal-less jitter attenuation that complies with the most stringent standards. Each channel also provides internal AMI/B8ZS/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.
