5 V CATV Line Driver Coarse Step Output Power Control

GENERAL DESCRIPTION The AD8322 is a low-cost, digitally controlled variable gain amplifier optimized for coaxial line driving applications such as cable modems that are designed to the MCNS-DOCSIS upstream standard. An 8-bit serial word determines the desired output gain over a 42.14 dB range, wi

5 V有線電視(CATV)線路驅(qū)動器，內(nèi)置大步進輸出功率控制功能

AD8322是一款低成本、數(shù)字控制式可變增益放大器，并針對同軸線路驅(qū)動應用進行了優(yōu)化，如根據(jù)MCNS-DOCSIS上行標準設計的電纜調(diào)制解調(diào)器等。所需輸出增益由8比特串行字決定，輸出增益范圍為42 dB，增益變化為6 dB/LSB。\n\nAD8322內(nèi)置0 dB至-42 dB的數(shù)字控制式可變衰減器，衰減器前面接低噪聲、固定增益緩沖器，后面接低失真、高功率放大器。在DOCSIS調(diào)制解調(diào)器應用中，AD8322與一些解調(diào)器上提供的衰減器配合，支持DOCSIS所要求的50 dB范圍。AD8322接受差分或單端輸入信號。輸出可驅(qū)動75 Ω額定負載，如同軸電纜等，不過也可驅(qū)動其它負載。本產(chǎn)品提供評估板，
