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 Euro-DOCSIS 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.

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
      Transmit-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 Driver
