For boundary frequencies, use the more restrictive specifications.
DLL Outputs are used in these instances to describe the outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV.
DFS Outputs are used in these instances to describe the outputs: CLKFX and CLKFX180.
If both DLL and DFS outputs are used, follow the more restrictive specifications.
The DCM must be reset if the clock input clock stops for more than 100 ms.
These values also apply when using both DLL and DFS outputs.
