DLL Timing Parameters
Because of the difficulty in directly measuring many internal
timing parameters, those parameters are derived from
benchmark timing patterns. The following guidelines reflect
DLL Clock Tolerance, Jitter, and Phase Information
All DLL output jitter and phase specifications were deter-
mined through statistical measurement at the package pins
using a clock mirror configuration and matched drivers.

Output Jitter is cycle-to-cycle jitter measured on the DLL output clock, 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 and 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 due to DLL alone (excluding input clock jitter).
