The PLL1 and 2 page shows the operating frequencies of the PLL1 and PLL2. In distribution mode, the CLKin1 frequency will directly be connected to the VCO/clock distribution path frequency. In addition to the basic PLL dividers and controls, when the PLLX_NCLK_MUX selects the feedback mux as a source, 0-delay modes are achieved. When enabling 0-delay red text will help guide the user through properly setting up 0-delay mode.
When using dual PLL mode, the OSCin Source combo box can be set to External VCXO which links the OSCin frequency with the external VCXO frequency. When using single PLL2 mode, the OSCin Source combo box can be set to Independent to allow the OSCin frequency to be unlinked from the external VCXO frequency.
