Additional Details

The 4046BCM contains a low-power VCO, a source follower, and three phase comparators. The VCO frequency is determined by external components (resistor and capacitor). The three phase comparator outputs provide different phase detection characteristics, allowing the designer to select the most suitable output for a given application. The device is available in a SOIC (Small Outline Integrated Circuit) package.

Operating Conditions: The recommended operating voltage (VDD) is between 3V and 15V. The VCO frequency range is determined by external components. Consult the Fairchild/ON Semiconductor datasheet for detailed specifications, including VCO characteristics, phase comparator outputs, and power consumption data.
