DLL specifications apply when using any of the DLL outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, or CLKDV.
When operating independently of the DLL, the DFS supports lower CLKIN_FREQ_DLL frequencies. See
The CLKIN_DIVIDE_BY_2 attribute increases the effective input frequency range. When set to TRUE, the input clock frequency is divided by two as
it enters the DCM. Input clock frequencies for the clock buffer being used can be increased up to the F
BUFIO2 limits). When used with CLK_FEEDBACK=2X, the input clock frequency matches the frequency for CLK2X, and is limited to
CLKOUT_FREQ_2X.
CLKIN_FREQ_DLL input jitter beyond these limits can cause the DCM to lose LOCK, indicated by the LOCKED output deasserting. The user must
then reset the DCM.
When using both DCMs in a CMT, both DCMs must be LOCKED.
