TX_CLK clock period 10 Mbps
TX_CLK clock period 100 Mbps
TX_CLK duty cycle
TX_CLK to MII data TXD[3:0], TX_ER, TX_EN delay
TX_CLK data clock rise time, VIL(min) to VIH(max)
TX_CLK data clock fall time, VIH(max) to VIL(min)
Note:
1. The symbols used for timing specifications herein follow the pattern of t
(reference)(state)
t
(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 example, the subscript of t
(TX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
