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. This symbol is used to represent the external GTX_CLK125 and does not follow the original symbol naming convention.

3. In rev. 2.0 silicon, due to errata, tTTKHDX minimum is 0.7 ns for UCC1. Refer to Errata QE_ENET19 in Chip Errata for the

MPC8360E, Rev. 1.
