General Description

The AD8326 is a high-output power, digitally controlled, variable gain amplifier optimized for coaxial line driving applications such as data and telephony cable modems that are designed to the MCNS-DOCSIS upstream standard.

An 8-bit serial word determines the desired output gain over a 53.5 dB range resulting in gain change
