MAX3801

19-1999; Rev 4; 7/04 3.2Gbps Adaptive Equalizer MAX3801 General Description The MAX3801 is a +3.3V adaptive cable equalizer designed for coaxial and twin-axial cable point-to-point communications applications. The equalizer includes differential CML data inputs and outputs, a loss-of-signal (LOS) output, and a cable integrity monitor (CIM) output. The adaptive cable equalizer is capable of equalizing differential or single-ended signals at data rates up to 3.2Gbps. It automatically adjusts to attenuation caused by skin-effect losses of up to 30dB at 1.6GHz. The equalizer effectively extends the usable length of copper cable in high-frequency interconnect applications. The MAX3801 is available in a 24-pin QFN package with exposed pad and consumes only 125mW at +3.3V.
