3.2Gbps Adaptive Equalizer
and Cable Driver
General Description
The MAX3800 is a +3.3V adaptive cable equalizer and
cable driver implemented together on a single chip. It is
designed for coaxial and twin-axial cable point-to-point
communications applications. The driver features differ-
ential current-mode logic (CML) inputs and outputs as
well as adjustable output amplitude. The equalizer
includes differential CML data inputs and outputs, a
loss-of-signal (LOS) output, and a cable integrity moni-
tor (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 cop-
per cable in high-frequency interconnect applications.
The MAX3800 is available in a 32-pin TQFP package
with exposed pad and consumes only 200mW at
+3.3V. The driver can be disconnected from the power
supply when it is not needed, resulting in a 40% reduc-
tion in supply current.
