PLL1 and 2 Page
The
PLL1 and PLL2
page shows the frequencies that the PLL1 and PLL2 operate at. 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.
