DS25BR120,pdf datasheet (3.125

The DS25BR120 is a single channel 3.125 Gbps LVDS buffer
optimized for high-speed signal transmission over lossy FR-4
printed circuit board backplanes and balanced metallic cables.
Fully differential signal paths ensure exceptional signal
integrity and noise immunity.
The DS25BR120 features four levels of pre-emphasis (PE)
for use as an optimized driver device. Other LVDS devices
with similar IO characteristics include the following products.
The DS25BR110 features four levels of equalization for use
as an optimized receiver device, while the DS25BR100 features
both pre-emphasis and equalization for use as an optimized
repeater device. The DS25BR150 is a buffer/repeater
with the lowest power consumption and does not feature
transmit pre-emphasis nor receive equalization.
