DESCRIPTION

The DS25BR110 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. A fully

differential signal path ensures exceptional signal

integrity and noise immunity.

The DS25BR110 features four levels of receive

equalization (EQ), making it ideal for use as a

receiver device. Other LVDS devices with similar IO

characteristics include the following products. The

DS25BR120 features four levels of pre-emphasis for

use as an optimized driver 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.

Wide input common mode range allows the receiver

to accept signals with LVDS, CML and LVPECL

levels; the output levels are LVDS. A very small

package footprint requires minimal space on the

board while the flow-through pinout allows easy board

layout. The differential inputs and outputs are

internally terminated with a 100Ω resistor to lower

device input and output return losses, reduce

component count, and further minimize board space.
