TBI AC Timing Specifications
This section describes the TBI transmit and receive AC timing specifications.
9.2.4.1
TBI Transmit AC Timing Specifications
Table 9-9 provides the TBI transmit AC timing specifications.
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 tim-
ing (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, t
TTKHDX 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 repre-
sentation 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. Guaranteed by design.
