Notes:
1. In general, the clock reference symbol representation for this section is based on the symbols RGT to represent RGMII and
RTBI timing. For example, the subscript of tRGT represents the TBI (T) receive (RX) clock. 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).
2. 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.
3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively.
4. 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 tRGT of the lowest speed transitioned
between.
5. Guaranteed by characterization.
6. In rev 1.0 silicon, due to errata, tSKRGT is -650 ps (min) and 650 ps (max). Please refer to “eTSEC 10” in the device errata
document.
