DS90LV004
4-Channel LVDS Buffer/Repeater with Pre-Emphasis
General Description
The DS90LV004 is a four channel 1.5 Gbps LVDS buffer/re-
peater. High speed data paths and flow-through pinout mini-
mize 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 performance and
minimize board space. The repeater function is especially
useful for boosting signals for longer distance transmission
over lossy cables and backplanes.
