Description The NB3L8543S is a high performance, low skew 1- to- 4 LVDS
Clock Fanout Buffer. The NB3L8543S Features a multiplexed input which can be driven by either a differential or single- ended input to allow for the distribution of a lower speed clock along with the high speed system clock.
The CLK_SEL pin will select the differential CLK and CLK inputs when LOW (or left open and pulled LOW by the internal pull- down resistor). When CLK_SEL is HIGH, the differential PCLK and PCLK inputs are selected.
The mon clock enable pin, CLK_EN, is synchronous so that the outputs...
