1. This implies that PC board design requires clocks to be routed so that an additional trace delay of greater

than 1.5 ns is added to the associated clock signal.

2. For 10 Mbps and 100 Mbps Tcyc scales to 400 ns +/– 40 ns and 40 ns +/– 4 ns respectively.
3. Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet’s

clock domain, as long as minimum duty cycle is not violated and stretching occurs for no more than three
Tcyc of the lowest speed transitioned between.
