MAX3800

3.2Gbps Adaptive Equalizer and Cable Driver

Industry's First 3.2Gbps Adaptive Cable Equalizer/Driver


Please check latest availability status for a specific part variant.

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 differential 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 (active-low 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 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% reduction in supply current.
