The following figure provides the AC test load for the UTOPIA/POS.
Figure 70. UTOPIA/POS AC Test Load
Figure 71 and Figure 72 represent the AC timing from Table 80. 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.
The following figure shows the UTOPIA/POS 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 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/POS
outputs internal timing (UI) for the time tUtopia memory clock reference (K) goes from the high state (H) until outputs (O) are
invalid (X).
