REF_CLK clock rise time, VIL(min) to VIH(max)
REF_CLK 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
(V) relative to the t
receive timing (RMR) with respect to the time data input signals (D) went invalid (X) relative to the t
reference (K) going to the low (L) state or hold time. Note that, in general, the clock reference symbol representation
is based on three letters representing the clock of a particular functional. For example, the subscript of t
represents the RMII (RM) reference (X) clock. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
