Introduction

Pin Configurable/Selectable Oscillators are custom-made oscillators, often used to provide highly accurate frequencies with precision over a wide range of output frequencies. They are one-time programmable oscillators, which come pre-configured to a predetermined frequency, and can then be adapted for fine tuning, via their pins and select options. 554PC000524DGR is such a customised oscillator specifically designed and manufactured to cover a wide range of applications in frequency control, comprising inputs and outputs that can be programmed to suit individual requirements.

Application Field

The 554PC000524DGR is designed to be used in a variety of applications in industry, such as radio, wireless communications, navigation and multimedia. This customized oscillator offers several advantages over conventional oscillators in terms of performance, versatility and cost efficiency. It is a miniature and low-power oscillator that operates at frequencies ranging from 0.1 kHz to 100 MHz, and uses Phased Locked Loop (PLL) technology for frequency locking. This makes it ideal for use in practical applications where fast, accurate and low-power performance is required.On the other hand, its tiny size makes it suitable for use in miniature devices and circuit boards. Additionally, its low phase noise and low jitter offers excellent immunity to noise and other radio interference.

Working principle

The 554PC000524DGR utilizes three pins (PDIN, PDOUT, PDR) combined with select options and user switchable outputs to achieve its outstanding performance. When configuring the device, the PDIN and PDOUT pins are used to select the desired frequency, while the PDR pin is used to switch between external crystal or internal high-stability oscillator reference frequencies.Once configured, the device will lock to the selected frequency and maintain stability over a wide temperature range and over long periods of time, making it extremely reliable and accurate. Additionally, the device offers high immunity against environmental noise and EMI, making it suitable for demanding applications.Finally, the device includes a wide-range of selectable output formats, which enables it to be used with both analog and digital devices. This makes it an ideal solution for applications where a reliable frequency is required.

Conclusion

In conclusion, the 554PC000524DGR is an advanced pin-programmable oscillator designed specifically for frequency control applications. It offers excellent performance, versatility, low power consumption and cost-efficiency. This oscillator can be programmed to provide high-accuracy frequency output over a wide range of output frequencies and a wide variety of output formats. This combination makes it ideal for a range of applications in radio, wireless communications, navigation and multimedia.
