Note:
1.
AC characteristics apply for parallel output termination of 50

.
2. Violation of the 1.0 nS maximum input rise and fall time limit will affect the device propagation delay, device-to-device skew, reference input pulse
width, output duty cycle and maximum frequency specifications.
3. Setup and hold times are referenced to the falling edge of the selected clock signal input.
4. Output pulse skew is the absolute difference of the propagation delay times: | t
