Notes:
1. The symbols used for timing specifications herein follow the pattern of t
2. Setup and hold time of even numbered RCG are measured from riding edge of PMA_RX_CLK1. Setup and hold time of

respect to the time data input signals (D) went invalid (X) relative to the t
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
the latter convention is used with the appropriate letter: R (rise) or F (fall). For symbols representing skews, the subscript
is skew (SK) followed by the clock that is being skewed (TRX).
odd numbered RCG are measured from riding edge of PMA_RX_CLK0.
