Notes:
1. The symbols for timing specifications follow the pattern 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, tGTKHDV symbolizes GMII transmit timing (GT)
with respect to the tGTX clock reference (K) going to the high state (H) relative to the time date input signals (D) reaching the
valid state (V) to state or setup time. Also, tGTKHDX symbolizes GMII transmit timing (GT) with respect to the tGTX clock
reference (K) going to the high state (H) relative to the time date input signals (D) going invalid (X) or hold time. In general,
the clock reference symbol is based on three letters representing the clock of a particular function. For example, the subscript
of tGTX represents the GMII(G) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
2. This symbol represents the external GTX_CLK125 signal and does not follow the original symbol naming convention.
