DS90LV004
4-Channel LVDS Buffer/Repeater with Pre-Emphasis
General 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
National’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 perfor-
mance and minimize board space. The repeater function is
especially useful for boosting signals for longer distance
transmission over lossy cables and backplanes.
