MII AC Timing Specifications
This section describes the MII transmit and receive AC timing specifications.
8.2.2.1
MII Transmit AC Timing Specifications
Table 27 provides the MII transmit AC timing specifications.
Figure 10 shows the MII transmit AC timing diagram.

Note:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMTKHDX symbolizes MII transmit timing
(MT) for the time tMTX clock reference (K) going high (H) until data outputs (D) are invalid (X). In general, the clock reference
symbol is based on two to three letters representing the clock of a particular function. For example, the subscript of tMTX
represents the MII(M) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate letter:
R (rise) or F (fall).
