PRODUCTION DATA
PLLatinum Sim allows loading a custom phase noise plot for reference inputs. For improved accuracy in simulation and optimum loop filter design, load these custom noise profiles. After loading a phase noise plot, user must recalculate the recommended loop filter design. PLLatinum Sim returns solutions with high reference or phase detector frequencies by default. In PLLatinum Sim the user can increase the reference divider to reduce the frequency if desired.
The next section discusses PLL loop filter design specific to this example using default phase noise profiles.
PLLatinum Sim provides optimal loop filters upon selecting a solution from the solution list to simulate for the first time. Anytime PLL related inputs change, like input phase noise, charge pump current, divider values, and so forth, using the tool to recalculate the optimal loop filter component values is best.
