Feedback Clock Path Delay Variation
CLKFB off-chip feedback
“DLL outputs” is used here to describe the outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV.
If both DLL and CLKFX outputs are used, follow the more restrictive specification.
If DCM phase shift feature is used and CLKIN frequency > 200 Mhz, CLKIN duty cycle must be within ±5% (45/55 to 55/45).
