The DS25BR100 and DS25BR101 are single channel 3.125 Gbps LVDS buffers 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 DS25BR100 and DS25BR101 feature transmit pre-emphasis (PE) and receive equalization (EQ), making them ideal for use as a repeater 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 DS25BR110 features four levels of equalization for use as an optimized receiver 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. On the DS25BR100 the differential input and output is internally terminated with a 100Ω resistor to lower return losses, reduce component count and further minimize board space. For added design flexibility the 100Ω input terminations on the DS25BR101 have been eliminated. This elimination enables a designer to adjust the termination for custom interconnect topologies and layout.
