Description

DISTORTION dBc The AD8323 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 53.5 dB range resulting in gain changes of 0.7526 dB/LSB.The AD8323 comprises a digitally controlled variable attenuator of 0 dB to 53.5 dB, which is preceded by a low noise, fixed gain buffer and is fol
