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.
When using the DCMs CLKIN_DIVIDE_BY_2 attribute these values should be doubled.
4.
When using a CLKIN frequency > 400 MHz and the DCMs CLKIN_DIVIDE_BY_2 attribute, the CLKIN duty cycle must be within ±5% (45/55 to
55/45).
5.
The DCM must be reset if the clock input clock stops for more than 100 ms.
6.
These values also apply when using both DLL and DFS outputs.
