MAX3803 Datasheet, PDF (1/8 Pages) Maxim Integrated Products – DC-Coupled, UCSP 3.125Gbps Equalizer
19-2699; Rev 0; 2/03
DC-Coupled, UCSP 3.125Gbps Equalizer
General Description
The MAX3803 equalizer automatically provides com-
pensation for transmission-medium losses encountered
with FR4 stripline and cable in an incredibly small 2mm
× 2.5mm package. It is ideal for backplane applications
requiring up to 40in between the line card and the
switch card or up to 10m of twin ax cable between
racks. Its small size provides placement and routing
flexibility. The CML inputs and outputs are DC-coupled
and can be terminated to a supply as low as +1.1V.
The MAX3803 operates from 0°C to +85°C and con-
sumes 160mW at +3.3V.
Applications
Backplane Interconnect
Rack-to-Rack Interconnect
Common-Mode Voltage Translation
(LVDS, PECL, or CML)
