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