MII/7-WIRE Interface Timing Specs
The following timing specs are defined at the chip I/O pin and must be translated appropriately to arrive at timing
specs/constraints for the EMAC_10_100 I/O signals.
The following timing specs meet the requirements for MII and 7-Wire style interfaces for a range of transceiver devices. If this
interface is to be used with a specific transceiver device the timing specs may be altered to match that specific transceiver.

Reference Manual. Also specific guidelines may need to be followed when operating the system PLL below certain
frequencies.
2 Max cycle rate is determined by CLKIN and how the user has the system PLL configured.
3 All signals defined as PCI bused signals. Does not include PTP (point-to-point) signals.
4 PCI 2.2 spec does not require an output hold time. Although the MCF547X may provide a slight amount of hold, it
is not required or guaranteed.
5 PCI 2.2 spec requires zero input hold.
6 These signals are defined at PTP (Point-to-point) in the PCI 2.2 spec.
