RXD[7:0], RX_DV, RX_ER hold time to RX_CLK
RX_CLK clock rise time, VIL(min) to VIH(max)
RX_CLK clock fall time, VIH(max) to VIL(min)
Note:
1. The symbols used for timing specifications herein follow the pattern of t
for inputs and t
receive timing (GR) with respect to the time data input signals (D) reaching the valid state (V) relative to the t
(K) going to the high state (H) or setup time. Also, t
input signals (D) went invalid (X) relative to the t
general, the clock reference symbol representation is based on three letters representing the clock of a particular functional.
For example, the subscript of t
used with the appropriate letter: R (rise) or F (fall).
