Maxim Integrated MAX3802
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.GENERAL DESCRIPTION
FEATURES
o Single 3.3V Operation o Four Independent Equalizers and Drivers o 725mW at 3.3V Typical Power Dissipation o Data Rates Up to 3.2Gbps o Equalizer Automatically Adjusts for Different Cable Lengths o 0 to 30dB Equalization at 1.6GHz (3.2Gbps) o Loss-of-Signal ( LOS ) Indicator o On-Chip Input and Output Terminations o Low External Component Count o 0°C to +85°C Operating Temperature Range o ESD Protection on Cable Inputs and Outputs MAX3802 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 skineffect losses of 30dB at 1.6GHz. The equalizer effectively extends the usable length of copper cable in high-frequency interconnect applications.APPLICATIONS
