3.2Gbps Quad Adaptive Cable Equalizer with Cable Driver

Quad 3.2Gbps Adaptive Equalizer Extends Reach

Please check latest availability status for a specific part variant.


The MAX3802 has four independent adaptive cable equalizers and cable drivers on a single chip. It is designed for coaxial and twin-axial cable point-to-point scrambled-data communication applications. The driver features differential current-mode logic (CML) inputs and outputs. The equalizer includes differential CML data inputs and outputs and a TTL loss-of-signal (active-low LOS) output.

The adaptive cable equalizer can equalize differential or single-ended signals at data rates up to 3.2Gbps. It automatically adjusts to attenuation caused by skin-effect losses of 30dB at 1.6GHz. The equalizer effectively extends the usable length of copper cable in high-frequency interconnect applications.
