Notes:
1. Note that, 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. The RGMII specification requires that PC board designer add 1.5 ns or greater in trace delay to the RX_CLK in order to
meet this specification. However, as stated above, this device functions with only 1.0 ns of delay.
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. Guaranteed by design.
7. Signal timings are measured at 0.5 and 2.0 V voltage levels.
