CAUTION
The I/O Timings provided in this section are valid only for some GMAC usage modes when the corresponding Virtual I/O Timings or Manual I/O Timings are configured as described in the tables found in this section.
Table 7-75, Table 7-75 and Figure 7-56 present timing requirements for MDIO.
No | PARAMETER | DESCRIPTION | MIN | MAX | UNIT |
---|---|---|---|---|---|
MDIO1 | tc(MDC) | Cycle time, MDC | 400 | ns | |
MDIO2 | tw(MDCH) | Pulse Duration, MDC High | 160 | ns | |
MDIO3 | tw(MDCL) | Pulse Duration, MDC Low | 160 | ns | |
MDIO4 | tsu(MDIO-MDC) | Setup time, MDIO valid before MDC High | 90 | ns | |
MDIO5 | th(MDIO_MDC) | Hold time, MDIO valid from MDC High | 0 | ns |
NO | PARAMETER | DESCRIPTION | MIN | MAX | UNIT |
---|---|---|---|---|---|
MDIO6 | tt(MDC) | Transition time, MDC | 5 | ns | |
MDIO7 | td(MDC-MDIO) | Delay time, MDC low to MDIO valid | -150 | 150 | ns |
In Table 7-77 are presented the specific groupings of signals (IOSET) for use with GMAC MDIO signals.
