6. tJIT (cc) is defined as the absolute difference in clock period between two consecutive clock cycles:
tJIT (cc) = Max. of |tCK
j+1
tCK

|
tJIT (cc) is defines the cycle to cycle jitter when the DLL is already locked. tJIT (cc, lck) uses the same
definition for cycle to cycle jitter, during the DLL locking period only. tJIT (cc) and tJIT (cc, lck) are not
subject to production test.
7. tERR (nper) is defined as the cumulative error across multiple consecutive cycles from tCK (avg).
tERR (nper) is not subject to production test.

8. These parameters are specified per their average values, however it is understood that the following
relationship between the average timing and the absolute instantaneous timing hold at all times.
