FUNCTIONAL DESCRIPTION
The DS10BR254 is a 1.5 Gbps 1:4 LVDS repeater optimized for high-speed signal routing and distribution over
lossy FR-4 printed circuit board backplanes and balanced cables.

Input Interfacing
The DS10BR254 accepts differential signals and allows simple AC or DC coupling. With a wide common mode
range, the DS10BR254 can be DC-coupled with all common differential drivers (i.e. LVPECL, LVDS, CML). The
following three figures illustrate typical DC-coupled interface to common differential drivers. Note that the
DS10BR254 inputs are internally terminated with a 100
Ω resistor.
