UTOPIA/POS
Figure 62 provides the AC test load for the Utopia.
Figure 62. Utopia AC Test Load
Figure 63 through Figure 64 represent the AC timing from Table 74. 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.
Figure 63 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).
