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. Signal timings are measured at 0.7 V and 1.9 V voltage levels.
3. Guaranteed by design.
