CAUTION
The IO Timings provided in this section are only valid for some GMAC usage modes when the corresponding Virtual IO Timings or Manual IO Timings are configured as described in the tables found in this section.
Table 7-76, Table 7-76 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 |
Figure 7-56 GMAC MDIO diagrams In Table 7-78 are presented the specific groupings of signals (IOSET) for use with GMAC MDIO signals.
