RGMII AC Timing Specifications
Table 45 presents the RGMII AC timing specifications for applications requiring an on-board delayed clock.
Table 46 presents the RGMII AC timing specification for applications required non-delayed clock on board.

Notes:
1.
At recommended operating conditions with LVDD of 2.5 V +/- 5%.
2.
This implies that PC board design requires clocks to be routed such that an additional trace delay of greater than 1.5 ns is
added to the associated clock signal.
3.
GCR4 should be programmed as 0x00001004.
