Note 1: Tested with 100 MHz clock with outputs driving 4” long trace terminated with 2 pF Capacitors to ground.

2: Output Enable control (pin or register) is synchronous with the input clock and it takes four rising edges

before output gets enabled or disabled. Hence the minimum input frequency is greater than 0 Hz. Once

the outputs are enabled the input clock frequency can be reduced to 0 Hz.
