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 dri-
ver features differential current-mode logic (CML)
inputs and outputs. The equalizer includes differential
CML data inputs and outputs and a TTL loss-of-signal
(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 effec-
tively extends the usable length of copper cable in
high-frequency interconnect applications.
