UTOPIA/POS AC Timing Specifications

This figure provides the AC test load for the UTOPIA.

Figure 46. UTOPIA AC Test Load

These figures represent the AC timing from Table 56. Note that although the specifications generally reference the rising edge

of the clock, these AC timing diagrams also apply when the falling edge is the active edge.

This figure shows the UTOPIA timing with external clock.

Notes:

1. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal. Timings

are measured at the pin.

2. 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, tUIKHOX symbolizes the UTOPIA

outputs internal timing (UI) for the time tUTOPIA memory clock reference (K) goes from the high state (H) until outputs (O)

are invalid (X).

3. In rev. 2.0 silicon, due to errata, tUEIVKH minimum is 4.3 ns and tUEIXKH minimum is 1.4 ns under specific conditions. Refer

to Errata QE_UPC3 in Chip Errata for the MPC8360E, Rev. 1.
