The timings assume the following configuration:
DDR_SEL = (11)b
DSE (drive-strength) = (111)b
For 10 Mbps and 100 Mbps, T
For all versions of RGMII prior to 2.0; This implies that PC board design will require clocks to be routed such that an additional
delay of greater than 1.2 ns and less than 1.7 ns will be added to the associated clock signal. For 10/100, the max value is
unspecified.
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.
