These user-configurable clock outputs (CLKOUT0 through CLKOUT6) can be divided versions of the VCO phase outputs (user controllable) from 1 (bypassed) to 128. The input clock and output clocks can be phase aligned.
For possible configurations, see MMCM Use Models . In the MMCM, CLKOUT0 and CLKFBOUT can be used in fractional divide mode. All CLKOUT outputs can be used in non-fractional mode to provide a static or dynamic phase shift. In fractional mode, only fixed phase shift is allowed. See Static Phase Shift Mode (MMCM and PLL) for more information.
