CD4046BE Instructions

1. Supply Voltage:

   • The CD4046BE operates with a supply voltage range of 5V to 15V. Ensure that the supply voltage is within this range to avoid damage to the IC.

2. Input Signals:

   • The input signals should be within the range of -0.5V to V_CC + 0.5V. Exceeding these limits can cause damage to the IC.

3. Output Signals:

   • The output high level (V_OH) is typically around 3.5V when the supply voltage is 10V, and the output low level (V_OL) is typically around 0.4V. Ensure that the load current does not exceed 10mA to maintain these levels.

4. Power Dissipation:

   • The maximum power dissipation is 1000mW at 25°C ambient temperature. Ensure adequate heat dissipation if operating at higher temperatures or with higher power consumption.

5. Temperature Range:

   • The operating temperature range is from -40°C to 85°C. The storage temperature range is from -65°C to 150°C.

6. Capacitance:

   • The input capacitance is typically 10pF, and the output capacitance is typically 5pF. These values can affect the performance of the PLL, especially at high frequencies.

7. Phase Detectors:

   • The CD4046BE has two phase detectors:
     • Type 1 (XOR Gate): Provides a pulse-width modulated output.
     • Type 2 (Edge-Triggered): Provides a charge pump output.
   • Choose the appropriate phase detector based on your application requirements.

8. VCO (Voltage-Controlled Oscillator):

   • The VCO frequency range is from 1kHz to 100kHz with typical values of R_VCO = 10kΩ and C_VCO = 100pF. Adjust these values to achieve the desired frequency range.
   • The control voltage (V_CTRL) should be within the range of 0V to V_CC.

9. Layout Considerations:

   • Keep the layout compact and minimize the length of high-frequency signal traces to reduce noise and parasitic effects.
   • Use bypass capacitors (e.g., 0.1μF) close to the power pins to filter out noise.

10. Testing and Troubleshooting:

    • Verify the supply voltage and input signals before testing the IC.
    • Check the output signals with an oscilloscope to ensure they meet the expected levels.
    • If the PLL is not locking, check the VCO frequency range and phase detector settings.

By following these instructions, you can effectively use the CD4046BE in your phase-locked loop applications.
