MII AC Timing Specifications
This section describes the MII transmit and receive AC timing specifications.
9.2.3.1
MII Receive AC Timing Specifications
Table 9-7 provides the MII transmit AC timing specifications.
Notes:
1. The symbols used for timing specifications herein 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 t
MTX clock reference (K) going high (H) until data outputs (D) are invalid (X). Note that, in general, the clock
reference symbol representation is based on two to three letters representing the clock of a particular functional. For exam-
ple, 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).
2. Guaranteed by design.
Figure 9-6 shows the MII transmit AC timing diagram.
