Pin Configurable/Selectable Oscillators, such as 534FB000184DG, are commonly used in applications where multiple frequency selectivity is desirable and/or different output formats are needed, such as a low current sine wave output, or a square wave output with active pull-up and pull-down drivers. With integrated frequency selection, small package size, and low pin count, these devices offer many advantages over traditional oscillators.

Application Field of 534FB000184DG

The 534FB000184DG Pin Configurable/Selectable Oscillator is especially suited for automotive and industrial applications needing programmable frequencies, such as sensor interrogation, MCU (microcontroller) clock generation, and LCD/OLED backlighting controllers.

Thanks to its built-in frequency programmability and a maximum output frequency of 800MHz, the 534FB000184DG is also suitable for communication and broadcast applications such as WiFi, LTE, and 5G networks, radio broadcast, and test & measurement equipment.

It is also widely used in timing control applications, frequency correction, and radio frequency (RF) bootstrapping. Furthermore, its wide operating voltage range of 2.0V to 5.5V allows it to be used in systems needing a wide dynamic range of power supplies.

Working Principle of 534FB000184DG

The 534FB000184DG is a programmable oscillator, meaning that it can be configured by the user using pin configuration techniques. The oscillator consists of a circuit for detecting whether the pins are high or low, digital circuitry for sequentially selecting the output frequency, a feedback circuit, and a resonator.

The digitally programmed output frequency of the 534FB000184DG is determined when the pins are configured to a specific pattern, which is clocked into a shift register. The frequency is determined by the combination of the digital pulses that are passed to the oscillator.

The oscillator outputs a square wave signal whose frequency is determined by the amount of time it takes for the wave to go from high to low, called the period. The wave amplitude is determined by the voltage of the power supply and the logic levels set by the pin configuration chosen by the user.

The frequency stability is determined by the characteristics of the built-in resonator, which can be selected from a variety of temperatures, frequencies, and stability options. By choosing a resonator with the desired requirements, the accuracy and stability of the oscillator can be improved.
