Timing Characteristics (continued)

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 42A. OR2CxxA and OR2TxxA Internal Clock Delay

OR2CxxA Commercial: VDD = 5.0 V ± 5%, 0 °C

≤ TA ≤ 70 °C; OR2CxxA Industrial: VDD = 5.0 V ± 10%, –40 °C ≤ TA ≤ +85 °C.

OR2TxxA Commercial: VDD = 3.0 V to 3.6 V, 0 °C

≤ TA ≤ 70 °C; OR2TxxA Industrial: VDD = 3.0 V to 3.6 V, –40 °C ≤ TA ≤

+85 °C.
