[ f_VCO \approx \frac3.7R_t \cdot C_t ]
Since LM565 is absent, use this equivalent:
: The LM565 is frequently missing from default Proteus versions. Many users report needing to find or create a custom SPICE model Import a 3rd Party Model to use it. Simulation Difficulty lm565 proteus
By adding a frequency divider in the feedback loop, the PLL can multiply an input frequency.
The formula is:
In the world of analog and mixed-signal simulation, few components are as versatile yet as misunderstood as the Phase-Locked Loop (PLL). Among the classic PLL integrated circuits, the (and its dual counterpart, the LM565C) stands out as a reliable, general-purpose device used for frequency synthesis, FM demodulation, and signal synchronization.
If the native model is missing or faulty, follow this proven process: [ f_VCO \approx \frac3
Features an internal Voltage-Controlled Oscillator (VCO) and a phase detector. Stability: High frequency stability of and power supply rejection. Working with LM565 in Proteus
