IDT™ / ICS™ LVCMOS CLOCK FANOUT BUFFER
MPC9446
3.3V AND 2.5V LVCMOS CLOCK FANOUT BUFFER
The time from the PLL controlled edge to the non controlled
edge, divided by the time between PLL controlled edges,
expressed as a percentage.
The pin-to-pin skew is defined as the worst case difference
in propagation delay between any two similar delay paths
within a single device.
