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

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 module.
