The values in this table are based on the operating conditions described in
The maximum variable phase shift range, MAX_STEPS, is only valid when the DCM has no initial fixed-phase shifting, that is, the PHASE_SHIFT
attribute is set to 0.
The DCM_DELAY_STEP values are provided at the end of
This limit only applies to applications that use the DCM DLL outputs (CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV). The DCM
DFS outputs (CLKFX, CLKFXDV, CLKFX180) are unaffected.

When CLKIN < 60 MHz, the maximum allowed
number of DCM_DELAY_STEP steps for a
given CLKIN clock period, where T = CLKIN
clock period in ns. When using
CLKIN_DIVIDE_BY_2 = TRUE, double the
clock-effective clock period.
When CLKIN 60 MHz, the maximum allowed
number of DCM_DELAY_STEP steps for a
given CLKIN clock period, where T = CLKIN
clock period in ns. When using
CLKIN_DIVIDE_BY_2 = TRUE, double the
clock-effective clock period.
