The recommended operating voltage range for the HEF4046BT,653 is 3 V to 15 V.
To ensure the PLL is properly locked, the VCO (Voltage-Controlled Oscillator) frequency should be within the specified range, and the loop filter components should be selected according to the datasheet recommendations.
The maximum clock frequency that the HEF4046BT,653 can handle is 25 MHz.
To minimize jitter, use a high-quality clock source, ensure proper power supply decoupling, and minimize noise on the VCO input.
Yes, the HEF4046BT,653 can be used as a VCO only by bypassing the PLL and using the VCO output directly.
