Determine the M and D Values
possible output frequencies for the second output frequency. Continue this process until all
the output frequencies are selected.
The constraints used to determine the allowed M and D values are shown in the following
equations:
Determining the input frequency can result in several possible M and D values. The next
step is to determine the optimum M and D values. The starting M value is first determined.
This is based off the VCO target frequency, the ideal operating frequency of the VCO.
The goal is to find the M value closest to the ideal operating point of the VCO. The
minimum D value is used to start the process. The goal is to make D and M values as small
as possible while keeping ƒ

General clock input.
Secondary clock input to dynamically switch the PLL reference clock.
Feedback clock input.
Signal controls the state of the input mux, High = CLKIN1, Low = CLKIN2
Asynchronous reset signal. The RST signal is an asynchronous reset for the PLL. The
PLL will synchronously re-enable itself when this signal is released (i.e., PLL re-
enabled). A reset is required when the input clock conditions change (e.g.,
frequency).
The dynamic reconfiguration address (DADDR) input bus provides a
reconfiguration address for the dynamic reconfiguration. When not used, all bits
must be assigned zeros.
