58.6.9.1 Ethernet MAC MDIO Interface Timings

Table 58-35. Ethernet MAC MDIO Interface Timings
Symbol	Parameter	Min	Max	Unit
f_MDC	MDC clock frequency⁽¹⁾	–	10	MHz
EMAC₁	MDIO input data setup time before MDC rising edge	10	–	ns
EMAC₂	MDIO input data hold time after MDC rising edge	0	–	ns
EMAC₃	MDC falling edge to MDIO output data valid	0	25	ns

Note:

The Ethernet PHY should be selected to comply with f_MDC = f_MCK/64.
If f_MCK = 200 MHz, f_MDC(min) = 200/64= 3.125 MHz.
