Pin Configurable/Selectable Oscillators

Oscillators are specialized electrical circuits which produce periodic electrical signals without any additional external input. Variations on this circuit include pin configurable and selectable oscillators, which are capable of producing a wide variety of output frequencies. Pin configurable oscillators (such as the 534FA000661DG) are highly configurable, while selectable oscillators allow the user to select from a range of pre-determined frequencies. Both types of oscillators rely on the same basic operating principles, but differ in the way they are configured to produce different frequencies.

534FA000661DG Application Field

The 534FA000661DG is a tunable, low-cost oscillator specifically designed for use in communications systems, such as cellular phones and Wi-Fi routers. Its two-pin configuration makes it ideal for applications requiring minimal external circuitry. The 534FA000661DG features a built-in PLL for frequency tuning and a fully adjustable frequency range of up to 153.6 MHz. Its output signal strength is greater than -87dBm, along with low phase jitter and noise. Additionally, the 534FA000661DG is offered in a tiny 0.2mm2 package, making it ideal for applications where board space is limited.

534FA000661DG Working Principle

The 534FA000661DG oscillator uses a crystal oscillator to produce a specific frequency. A crystal is a small piece of quartz whose physical properties allow it to vibrate at a specific frequency when supplied with an electrical current. The crystal oscillator consists of an L-C circuit, where the crystal is connected in parallel across an inductor (L) and a capacitor (C). When a voltage is applied across the L-C circuit, the crystal begins to vibrate, and this vibrating current is amplified by a transistor to become the output signal. The 534FA000661DG circuit features a PLL loop for frequency tuning, which allows for precise control over the output frequency. The PLL loop consists of a phase detector, a low pass filter, and a voltage-controlled oscillator (VCO). The phase detector compares the frequency of the input signal to the frequency of the VCO, and when they are not in phase, the phase detector will send an error signal to the low pass filter. The low pass filter amplifies the error signal, and the VCO is adjusted accordingly. This results in a precisely controlled, adjustable output frequency.

Conclusion

Pin configurable and selectable oscillators offer a range of uses, from providing frequency stability in communications systems to controlling digital displays in consumer electronics. The 534FA000661DG is an example of a pin configurable oscillator, which is particularly well suited for use in smaller electronics due to its low power consumption and small size. Its combination of a crystal oscillator and a PLL loop allows for precise frequency tuning and a wide range of output frequencies.
