Examples include ACO crystal oscillators and quartz crystals, clock synchronizers, telecom equipment, radar systems, servo motors, motion controllers, and process controllers.

In terms of working principle, the 516FHB000132AAGR uses a PLL circuit to generate precise frequencies. This circuit multiplies or divides an input frequency to generate an output frequency. The output frequency can then be adjusted as needed by adding or subtracting a portion of the input frequency.

The circuit is composed of two basic parts: the multiplication-by-integers and the fractional-N frequency synthesizer. The multiplier-by-integers circuit uses capacitors and inductors to create a high-Q LC tank circuit. This tank circuit is used to control the frequency of an oscillator, which is then amplified with a power amplifier.

The fractional-N frequency synthesizer makes use of a digital loop filter and a voltage-controlled oscillator to generate precise frequencies. This loop filter is used to adjust the output frequency of the oscillator, so that it is always precisely tuned to the desired frequency. The voltage-controlled oscillator is used to detect the exact frequency of the input signal, and the loop filter will adjust the output frequency to match.

The advantages of using a pin configurable/selectable oscillator include its low price, small size, ease of use, and accuracy over temperature and voltage. By using this type of oscillator, users can configure the frequency they need, while keeping power consumption and output noise to a minimum.
