pairs. The part is designed for use in low voltage 3.3V

applications that require a large number of outputs to drive

precisely aligned, ultra low-skew signals to their destination.

The input is multiplexed from either LVDS or LVPECL (Low

Voltage Positive Emitter Coupled Logic) by the CLK_SEL

pin. The OE (Output Enable) 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.
