Example Data Input Setup and Hold Times Relative to a Forwarded Clock Input Pin,
situations where clock and data inputs conform to different standards, adjust the setup and hold values accordingly using the values
shown in
T
The timing values were measured using the fine-phase adjustment feature of the DCM. These measurements include CLK0 DCM jitter. Package
skew is not included in these measurements.
