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

(T) receive (RX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). For
symbols representing skews, the subscript SK followed by the clock that is being skewed (TRX).
