TX_CLK data clock fall (80%–20%)
Note:
1. The symbols for timing specifications follow the pattern of t
and t
(MT) for the time t
symbol is based on two to three letters representing the clock of a particular function. For example, the subscript of t
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).
