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, tTTKHDV symbolizes the TBI transmit
timing (TT) with respect to the time from tTTX (K) going high (H) until the referenced data signals (D) reach the valid state (V)
or setup time. Also, tTTKHDX symbolizes the TBI transmit timing (TT) with respect to the time from tTTX (K) going high (H) until
the referenced data signals (D) reach the invalid state (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 tTTX represents the TBI (T) 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 and does not follow the original symbol naming convention
