Notes:
1. The symbols used 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. 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 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. Data valid tGTKHDV to GTX_CLK Min setup time is a function of clock period and max hold time (Min setup = cycle time –
Max delay).
