(H) until the referenced data signals (D) reach the invalid state (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 t
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).
