Hi-Speed USB 2.0 to 10/100 Ethernet Controller

Datasheet

Table 4.13 Turbo MII Interface Timing Values

SYMBOL	DESCRIPTION	MIN	MAX	UNITS	NOTES

trxsetup	RXD and RXDV setup time prior to rising edge	5.5		ns	Note 4.14
	of RXCLK

trxhold	RXD and RXDV hold time after the rising edge	0		ns	Note 4.14
	of RXCLK

Note 4.14 These values satisfy the 10-ns setup and hold time requirements that are necessary for the Turbo MII specification.
