AD8328

Overview
DISTORTIONOBS(dBc) OLETE FEATURES Supports DOCSIS and EuroDOCSIS standards for reverse path transmission systems Gain programmable in 1 dB steps over a 59 dB range Low distortion at 60 dBmV output −57.
5 dBc SFDR at 21 MHz −54 dBc SFDR at 65 MHz Output noise level @ minimum gain 1.
2 nV/√Hz Maintains 300 Ω output impedance Tx-enable and Tx-disable condition Upper bandwidth: 107 MHz (full gain range) 5 V supply operation Supports SPI interfaces APPLICATIONS DOCSIS and EuroDOCSIS cable modems CATV set-top boxes CATV telephony modems Coaxial and twisted pair line drivers GENERAL DESCRIPTION The AD8328 is a low cost amplifier designed for coaxial line driving.
The features and specifications make the AD8328 ideally suited for MCNS-DOCSIS and EuroDOCSIS applications.
The gain of the AD8328 is digitally controlled.
An 8-bit serial word determines the desired output gain over a 59 dB range, resulting in gain changes of 1 dB/LSB.
The AD8328 accepts a differential or single-ended input si...
