Notes:
1.
DFS specifications apply when either of the DFS outputs (CLKFX or CLKFX180) is used.
2.
If both DFS and DLL outputs are used on the same DCM, follow the more restrictive CLKIN_FREQ_DLL specifications in Table 37.
3.
CLKIN input jitter beyond these limits may cause the DCM to lose lock.
4.
The DCM specifications are guaranteed when both adjacent DCMs are locked.
