DESCRIPTION

The DS10BR254 is a 1.5 Gbps 1:4 LVDS repeater

optimized for high-speed signal routing and

distribution over FR-4 printed circuit board

backplanes and balanced cables. Fully differential

signal paths ensure exceptional signal integrity and

noise immunity.

The device has two different LVDS input channels

and a select pin determines which input is active. A

loss-of-signal (LOS) circuit monitors both input

channels and a unique LOS pin is asserted when no

signal is detected at that input.

Wide input common mode range allows the switch to

accept signals with LVDS, CML and LVPECL levels;

the output levels are LVDS. A very small package

footprint requires a minimal space on the board while

the flow-through pinout allows easy board layout.

Each differential input and output is internally

terminated with a 100Ω resistor to lower device return

losses, reduce component count and further minimize

board space.
