3V Differential 2:1 MUX to 4 LVPECL Fanout Buffer Description The NB3L8533 is a low skew 1:4 LVPECL Clock fanout buffer designed explicitly for low output skew applications.
The NB3L8533 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 clock inputs, CLK and CLK, 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 common enable (CLK_EN) is synchronous so that the outputs will only be enabled/disabled when they are already in the LOW state.
This avoids any chance of generating a runt clock pulse when the device is enabled/disabled as can happen with an asynchronous control.
The internal flip flop is clocked on the falling edge of the input clock, therefore, all associated specification limi...
