产品描述

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 100? resistor to lower return losses, reduce component count and further minimize board space. For added design flexibility the 100? input terminations on the DS25BR101 have been eliminated. This elimination enables a designer to adjust the termination for custom interconnect topologies and layout.
