Notes:
1. The symbols used for timing specifications herein 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.Signal timings are measured at 0.7 V and 1.9 V voltage levels.
3.Guaranteed by characterization.
4.Guaranteed by design.
