Notes:
1.
PMCD outputs are not included in this table because they do not introduce jitter.
2.
Values for this parameter are available from the architecture wizard.

Notes:
1.
DLL Outputs are used in these instances to describe the outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV.
2.
DFS Outputs are used in these instances to describe the outputs: CLKFX and CLKFX180.
3.
CLKOUT_DUTY_CYCLE_DLL applies to the 1X clock outputs (CLK0, CLK90, CLK180, and CLK270) only if DUTY_CYCLE_CORRECTION=TRUE.
4.
The measured value includes the duty cycle distortion of the global clock tree.
