MII Transmission Timing

Validated with IEEE802.3 regulation.

The propagation delay for each twisted pair, measured from the MII connector to the PHY, shall not exceed 2.5 ns.

The variation in the propagation delay of the twisted pairs in a given cable bundle, measured from the MII connector to

the PHY, shall not exceed 0.1 ns.
