: Capable of frequency multiplication, division, and data synchronization. : Supports a wide power supply range ( ) and operates up to a maximum VCO frequency of UNL EE Shop Recommended Alternatives for Proteus
| Symptom in Proteus | Likely Cause | Fix | | :--- | :--- | :--- | | VCO output stuck at 0V or VCC | Missing SPICE model parameters (A0, VCO gain) | Edit model: Ensure GAIN parameter is defined. | | Simulation “timestep too small” error | High-frequency parasitic oscillations | Add series resistance (10Ω) to VCO output or tighten tolerance to 0.01%. | | Phase detector output is DC only | Input signal amplitude too low | Increase input sine wave to 3V p-p. | | VCO frequency does not change with input | Loop filter capacitor shorted or missing | Verify (C_f) connection from Pin 2 to GND. | lm565 proteus
If you need LM565 frequently, create your own Proteus part from the SPICE model using the Package Editor – then it will appear in Pick Devices permanently. : Capable of frequency multiplication, division, and data
From FM demodulation to frequency synthesis, the LM565 remains a timeless component, and mastering its simulation in Proteus will elevate your analog design projects to a professional level. | | Phase detector output is DC only
