DESCRIPTION
The DS90LV004 is a four channel 1.5 Gbps LVDS
buffer/repeater. High speed data paths and flow-
through pinout minimize internal device jitter and
simplify board layout, while configurable 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 are internally terminated with a 100Ω
resistor to improve performance and minimize board
space. The repeater function is especially useful for
boosting signals for longer distance transmission over
lossy cables and backplanes.
Typical Application
DS90LV004
Cable or Backplane
