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.
