• Dynamic phase shift. This feature allows you to change the phase relationship on the output clocks. • Dynamic reconfiguration. This feature allows you to change the programming of the primitive after device configuration. When this option is chosen, the clocking wizard uses only integer valu...
Dynamic Phase Shift Ports: Ports used when using the dynamic phase shift capability of the MMCM. PSCLK Input 1 Phase shift clock. PSDONE Output 1 Phase shift done. PSEN Input 1 Phase shift enable. PSINCDEC Input 1 Phase shift increment/decrement control. Feedback: Required ports to form...

In Virtex-5 and Spartan-6 the Phase Locked Loop (PLL) was introduced along with the DCM. The PLL is an analog clock management cell that can do almost everything the DCM can do with the exception of dynamic and fine phase shifting. However, it can do more precise frequency generation an...
