RGMII AC Timing Specifications
Table 34 presents the RGMII AC timing specifications for applications requiring an on-board delayed clock.
Table 35 presents the RGMII AC timing specification for applications required non-delayed clock on board.
Figure 25 shows the RGMII AC timing and multiplexing diagrams.

Notes:
1.
At recommended operating conditions with VDDIO of 2.5 V ± 5%.
2.
RGMII at 100 MHz support is guaranteed by design.
3.
Program GCR4 as 0x00000000.
4.
This implies that PC board design requires clocks to be routed such that an additional trace delay of greater than 1.5 ns and
less than 2.0 ns is added to the associated clock signal.
