Note that, in general, the clock reference symbol representation for this section is based on the symbols RGT to represent
RGMII and RTBI timing. Note also that the notation for rise (R) and fall (F) times follows the clock symbol that is being
represented. For symbols representing skews, the subscript is skew (SK) followed by the clock that is being skewed (RGT).
This implies that PC board design will require clocks to be routed such that an additional trace delay of greater than 1.5 ns
will be added to the associated clock signal.
For 10 and 100 Mbps, t
Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet's clock domains as long
as the minimum duty cycle is not violated and stretching occurs for no more than three t
