1 Timing specifications as per RGMII v2.0 standard.

2 Refer to example diagrams in the RGMII Timing Examples section.

3 When operating without RGMII internal delay, the printed circuit board (PCB) 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. For 10/100 Mbps, the max value is unspecified.

4 Hardware and software programmable internal delay may be enabled or disabled.

5 For 10 Mbps and 100 Mbps, tCYC scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively.
