Pin Configurable/Selectable Oscillators - 534CC000260DG

Pin Configurable/Selectable Oscillators are a niche type of frequency tuning oscillator that are used to increase the form factor and footprint of frequency control circuits. Compared to the more common tuning oscillator configurations, such as the voltage-controlled oscillator (VCO) or Pierce oscillators, Pin Configurable/Selectable Oscillators provide the same level of tuning accuracy but require fewer pins and consume much less physical space. In this article, we will discuss the application field and working principle of the 534CC000260DG Pin Configurable/Selectable Oscillator.

Application Field

The 534CC000260DG is designed to be an extremely compact solution for applications requiring fast-switching frequency control functions. The device contains an integrated variable frequency oscillator, which can be tuned with a single serial data stream input. This makes the 534CC000260DG an ideal choice for highly compact applications, such as digital receivers and transmitters, mobile communications systems, medical equipment, test instrumentation and industrial control systems. In addition to providing fast frequency switching and reducing the overall footprint of frequency control circuits, the 534CC000260DG also offers high-frequency accuracy and stability. This ensures consistent performance and reliability, even in the most demanding environments.

Working Principle

The working principle of the 534CC000260DG can be divided into two parts: variable-frequency oscillator design and voltage-controlled crystal oscillator (VCXO) tuning. The variable-frequency oscillator design is based on a stable coaxial high-Q oscillator, whereas the VCXO tuning circuit includes a fine-tuning digital pre-scaler and a divide-by-X crystal oscillator.The tuning process begins with a serial data stream input from the user, which is then converted into a clock signal. The clock signal is then divided by a digital pre-scaler, which determines the frequency of the output signal. The pre-scaler output is then fed into the VCXO circuit, which tunes the frequency of the output signal based on a voltage controlled oscillator. After the VCXO circuit has achieved the desired output frequency, the output signal is then divided by an X-divider circuit to achieve the final output frequency.

Conclusion

The 534CC000260DG Pin Configurable/Selectable Oscillator provides an efficient and compact solution for applications which require fast-switching frequency control functions. By combining a variable-frequency oscillator design and VCXO tuning, the 534CC000260DG can offer high-frequency accuracy and stability while using fewer pins and consuming less physical space. This makes the 534CC000260DG an ideal choice for applications such as digital receivers and transmitters, mobile communications systems, medical equipment, test instrumentation, and industrial control systems.
