Pin Configurable/Selectable Oscillators provide frequency selection within a particular product family without any additional components. The 552FD000270DG is an example of such a product. It is available in frequencies from 1.32MHz to 30MHz, while consuming less than 8mA of current as a typical application.

The working principle of the 552FD000270DG is based on a voltage-controlled oscillator (VCO), a parallel resonant oscillator, a reference crystal oscillator and a phase detector. The VCO control voltage is controlled by the phase detector, creating an oscillator output frequency that is determined by the VCO frequency and the reference crystal oscillator frequency. For example, when a reference crystal oscillator is producing a standard frequency of 8MHz, and the VCO control voltage is set to half the reference frequency (4MHz), the oscillator output frequency will be 12MHz.

The pins of the 552FD000270DG provide the ability to order the product with a specific center frequency or spread spectrum capability. Its center frequency is selected via a six-bit word pin configuration device, allowing for a range of 1.32MHz to 30MHz to be selected. Frequency spread spectrum capability can be set in 5% increments from 0.5% to 20%, tailoring the unit to meet specific applications. The total frequency spread can be adjusted from 16kHz to 5.2MHz (depending on the center frequency). The product also has a start-up time of 1ms, allowing quick response from the oscillator in critical applications.

The 552FD000270DG can be used in a variety of applications. It is commonly used in industrial and medical applications that require precise frequency control of a given signal, such as medical imaging, ultrasound systems and medical test equipment. Additionally, it can be used in military and aerospace applications, such as in radar systems and satellite communications. It is also used in consumer electronics, such as GPS systems, smart watches and wireless phones, as well as in automotive systems, such as tire pressure sensors, wireless tire pressure monitors and engine control modules.

The 552FD000270DG is a highly versatile and configurable oscillator that provides a wide range of frequencies and frequency spread spectrum capabilities. Its low power consumption and quick start-up time makes it an ideal choice for a variety of applications, including industrial, medical, military, aerospace, consumer and automotive.
