The 74HC4046ADB,112 operates as a CMOS PLL (Phase Locked loop) frequency synthesizer. It is most commonly used in applications such as automotive and industrial sensors, motor controllers and frequency synthesizers. The 74HC4046ADB,112 features two levels of truly digital features including programmable clock audio/video sync, advanced clock/timing/oscillator source selection, low-noise and low-power operation, as well as extremely accurate phase accuracy and frequency resolution.

The 74HC4046ADB,112 includes a phase detector, voltage-controlled oscillator (VCO), low-pass filter and voltage-controlled divider. The phase detector is a digital phase frequency Detector (PFD) that provides an input signal from another frequency source (reference clock) to the 74HC4046ADB,112. The VCO produces an output frequency that is dependent on the input signal frequency and the resistance of the low-pass filter.

The low-pass filter is used to limit the frequency of the output signal from the VCO. The voltage-controlled divider is used to match the input signal frequency with the output signal frequency from the VCO. By controlling the state of the voltage-controlled divider, the output signal frequency from the VCO can be adjusted within a certain range.

The programmable clock audio/video sync feature of the 74HC4046ADB,112 allows the output clock signal to be synchronized with an audio or video source. This synchronizaion feature is made possible through the use of an external reference clock (such as an internal or external audio or video signal) and its corresponding digital delay control. This feature is used to allow the 74HC4046ADB,112 to produce the necessary output signal frequency without causing overruns or underruns related to the source material.

The advanced clock/timing/oscillator source selection feature of the 74HC4046ADB,112 allows for the selection of a range of clock/timing/oscillator sources. This feature is useful for applications that require different clock frequencies (such as in embedded applications), as it allows the device to select from single frequencies, multiple frequencies, or a range of frequencies as desired.

The low-noise and low-power operation features of the 74HC4046ADB,112 enable it to run at much lower power levels than other similar devices. This feature also allows for lower noise emissions, which is an important factor in many applications such as those requiring a high degree of accuracy in the output signal.

Finally, the 74HC4046ADB,112 features extremely accurate phase accuracy and frequency resolution. This is achieved by using a combination of advanced digital signal processing techniques, resulting in a device that is well-suited for a wide variety of different applications.

In conclusion, the 74HC4046ADB,112 is an advanced PLL frequency synthesizer that is highly suitable for a variety of applications. Its digital features make it ideal for automotive, industrial and audio/video applications, while its low-noise, low-power and accurate phase accuracy and frequency resolution ensure that it is well-suited for precision applications as well.
