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.

The DS15BR400/DS15BR401 are powered from a single 3.3V supply and consume 578 mW (typ). They

operate over the full -40°C to +85°C industrial

temperature range and are available in space saving

WQFN-32 and TQFP-48 packages.
