Pin Configurable/Selectable Oscillators are special kinds of oscillators that allow users to customize their frequencies, achieving a range of features beyond what traditional oscillators offer. The 534AA000565DGR oscillator is a versatile, cost-effective solution in this category, providing multiple frequency configurations for a range of applications and needs. In this article, we will explore the application field and working principle of the 534AA000565DGR oscillator in detail.

The 534AA000565DGR is a compact for surface mount applications, offering wide frequency range and frequency field configurability. This allows the user to select their desired frequency from one of 3 standard frequencies, 1273MHz, 1563MHz, and 2515MHz, as well as a number of different frequencies within the range. The device also offers temperature stability, low jitter, and low phase noise, making it ideal for use in telecommunications and consumer electronics.

The device is available in a variety of packages, including a 3-pin SOT-89 and a 6-pin QFN. The 3-pin SOT-89 package offers the option of a selectable signal output frequency, while the 6-pin QFN offers the option of both selectable signal output frequencies as well as selectable control pins for additional flexibility. Both of these packages offer low power consumption, making the 534AA000565DGR ideal for battery-operated applications.

In terms of working principle, the 534AA000565DGR oscillator operates by combining a resistive-capacitive oscillator (RCO) circuit and a positive-emitter-coupled logic cell (PECL). The oscillations are generated by the RCO circuit, which contains a resistor and a capacitor arranged in a particular way. The resistor and capacitor form an RC circuit, where the resistor determines the frequency, and the capacitor filters out unwanted frequencies. The output from the oscillator is then shaped and amplified by the PECL logic cell, which provides a higher power output.

The oscillator also features an internal frequency synthesizer, allowing the user to configure a frequency other than the three pre-set frequencies, such as for custom applications. The oscillator also features slew rate control, which helps reduce jitter in the output signal. In addition, the device incorporates frequency pullability, which enables the user to adjust the output frequency within a certain range.

In short, the 534AA000565DGR oscillator offers a cost-effective solution for those looking for a highly configurable, pin selectable oscillator. Its small package, low power consumption, and wide range of frequency configurations make it an ideal choice for a variety of applications in the telecommunications and consumer electronics markets.
