Notes:
This clock delay is for a fully routed clock tree that uses the primary clock network. It includes both the input buffer delay and the clock routing
to the PFU CLK input. The delay will be reduced if any of the clock branches are not used.
Speed grades of -5, -6, and -7 are for OR2TxxA devices only.
Table 42B. OR2TxxB Internal Clock Delay
OR2TxxB Commercial: VDD = 3.0 V to 3.6 V, 0 °C ≤ TA ≤ 70 °C; OR2TxxB Industrial: VDD = 3.0 V to 3.6 V, –40 °C ≤ TA ≤
+85 °C.
