VersaNet Timing Characteristics
Global clock delays include the central rib delay, the spine delay, and the row delay. Delays do not include I/O input
buffer clock delays, as these are dependent upon I/O standard, and the clock may be driven and conditioned internally
by the CCC
clock delays within the device. Minimum and maximum delays are measured with minimum and maximum loading,
respectively.

Notes:
1. Value reflects minimum load. The delay is measured from the CCC output to the clock pin of a sequential element located in a lightly
2. Value reflects maximum load. The delay is measured on the clock pin of the farthest sequential element located in a fully loaded row
3. For the derating values at specific junction temperature and voltage supply levels, refer to
