DLL Clock Tolerance, Jitter, and Phase Information
All DLL output jitter and phase specifications determined through statistical measurement at the package pins using a clock
mirror configuration and matched drivers.

Input Clock Period Tolerance
Input Clock Jitter Tolerance (Cycle to Cycle)
Time Required for DLL to Acquire Lock
Output Jitter (cycle-to-cycle) for any DLL Clock Output
Phase Offset between CLKIN and CLKO
Phase Offset between Clock Outputs on the DLL
Maximum Phase Difference between CLKIN and CLKO
Maximum Phase Difference between Clock Outputs on the DLL
Output Jitter is cycle-to-cycle jitter measured on the DLL output clock and is based on a maximum tap delay resolution, excluding
input clock jitter.
Phase Offset between CLKIN and CLKO is the worst-case fixed time difference between rising edges of CLKIN and CLKO,
excluding Output Jitter and input clock jitter.
Phase Offset between Clock Outputs on the DLL is the worst-case fixed time difference between rising edges of any two DLL
outputs, excluding Output Jitter and input clock jitter.
Maximum Phase Difference between CLKIN an CLKO is the sum of Output Jitter and Phase Offset between CLKIN and CLKO,
or the greatest difference between CLKIN and CLKO rising edges due to DLL alone (excluding input clock jitter).
Maximum Phase DIfference between Clock Outputs on the DLL is the sum of Output JItter and Phase Offset between any DLL
clock outputs, or the greatest difference between any two DLL output rising edges sue to DLL alone (excluding input clock jitter).
Add 30% to the value for Industrial grade parts.
