Notes:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tTRDVKH symbolizes TBI receive timing
(TR) with respect to the time data input signals (D) reach the valid state (V) relative to the tTRX clock reference (K) going to
the high (H) state or setup time. Also, tTRDXKH symbolizes TBI receive timing (TR) with respect to the time data input signals
(D) went invalid (X) relative to the tTRX clock reference (K) going to the high (H) state. In general, the clock reference symbol
is based on three letters representing the clock of a particular function. For example, the subscript of tTRX represents the TBI
(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).
2. Setup and hold time of even numbered RCG are measured from the riding edge of PMA_RX_CLK1. Setup and hold times
of odd-numbered RCG are measured from the riding edge of PMA_RX_CLK0.
