FEATURES
DESCRIPTION
The DS15BR400/DS15BR401 are four channel LVDS
buffer/repeaters capable of data rates of up to 2
Gbps. High speed data paths and flow-through pinout
minimize internal device jitter and simplify board
layout, while pre-emphasis overcomes ISI jitter
effects from lossy backplanes and cables. The
differential inputs interface to LVDS, and Bus LVDS
signals such as those on TI's 10-, 16-, and 18- bit
Bus LVDS SerDes, as well as CML and LVPECL.
The differential inputs and outputs of the DS15BR400
are internally terminated with 100Ω resistors to
improve performance and minimize board space. The
DS15BR401 does not have input termination
resistors. The repeater function is especially useful
for boosting signals for longer distance transmission
over lossy cables and backplanes.
