Notes:
1. The symbols used for timing specifications herein 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
Hold)
