74VHC4046MX

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

74VHC4046MX is a PLL circuit designed to produce a high precision and low phase noise clock, or to generate a frequency synthesizer. It was developed and produced by STMicroelectronics, and is popularly used in many consumer products such as digital cameras and in automated control systems. The main features of this device is its low power consumption, high input tolerance and its output specific frequencies, making it a great choice for clock and frequency applications.

The 74VHC4046MX is composed of 3 major parts: the oscillator, the phase-locked loop (PLL) and the frequency synthesizer. The oscillator is a RC-based oscillator that produces a signal of frequency which is determined by the external components connected to it. This signal is then sent to the phase-locked loop (PLL) which is a type of electronic circuit used to extract and manipulate a signal’s phase or frequency. In the PLL the input signal is manipulated and the output signal frequency is locked to the input signal, creating the desired frequency output. Lastly, the signal generated by the PLL is sent to the frequency synthesizer, which is used to precisely generate custom frequencies.

The 74VHC4046MX is designed to deliver precise outputs with low power consumption, which makes it a popular choice in battery-powered devices. It also has a range of features including an adjustable DC voltage reference, a wide line regulation range and an adjustable noise level. In addition, the circuit is designed to be very tolerant of input signal jitter, making it suitable for generating very precise signals in noisy environments.

The 74VHC4046MX is a popular device for applications such as digital cameras, consumer audio/video systems, and automated control and monitoring systems. Its low power consumption and precise output make it an excellent choice for these applications. It can also be used for clock distribution, clock and frequency generation, frequency lock loop PLL applications and as a signal generator.

In conclusion, the 74VHC4046MX is a popularly used PLL circuit designed to produce precision and low phase noise clocks or frequency synthesizers. It can be used in many consumer product applications, such as digital cameras and automated control systems, and is designed to consume low power while delivering precise outputs.
