RXD[3:0], RX_DV, RX_ER hold time to RX_CLK
RX_CLK clock rise time, (20% to 80%)
RX_CLK clock fall time, (80% to 20%)

timing (MR) with respect to the time data input signals (D) reach the valid state (V) relative to the t
going to the high (H) state or setup time. Also, t
signals (D) went invalid (X) relative to the t
the clock reference symbol representation is based on three letters representing the clock of a particular functional. For
example, the subscript of t
with the appropriate letter: R (rise) or F (fall).
