Product details

Description

50 VOUT = 60dBmV @ MAX GAIN 55 DISTORTION dBc The AD8327 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 48.16 dB range resulting in gain changes of 6.02 dB/major carry.The AD8327 comprises a digitally controlled variable attenuator of 0 dB to 48.16 dB, which
