Notes: 1. tCK (avg) is calculated as the average clock period across any consecutive 200cycle window.  
N  
tCK(avg) =  
tCKj  
N
j =1  
N = 200  
2. tCH (avg) is defined as the average high pulse width, as calculated across any consecutive 200 high  
pulses.  
N  
tCH(avg) =  
tCHj (N ×tCK(avg))  
j =1  
N = 200  
3. tCL (avg) is defined as the average low pulse width, as calculated across any consecutive 200 low pulses.  
N  
tCL(avg) =  
tCLj (N × tCK(avg))  
j =1  
N = 200  
4. tJIT (duty) is defined as the cumulative set of tCH jitter and tCL jitter. tCH jitter is the largest deviation of  
any single tCH from tCH (avg). tCL jitter is the largest deviation of any single tCL from tCL (avg).  
tJIT (duty) is not subject to production test.  
tJIT (duty) = Min./Max. of {tJIT (CH), tJIT (CL)}, where:  
tJIT (CH) = {tCHj- tCH (avg) where j = 1 to 200}  
tJIT (CL) = {tCLj tCL (avg) where j = 1 to 200}  
5. tJIT (per) is defined as the largest deviation of any single tCK from tCK (avg).  
tJIT (per) = Min./Max. of { tCKj tCK (avg) where j = 1 to 200}  
tJIT (per) defines the single period jitter when the DLL is already locked. tJIT (per, lck) uses the same  
definition for single period jitter, during the DLL locking period only. tJIT (per) and tJIT (per, lck) are not  
subject to production test.
