Pin Configurable/Selectable Oscillators

Oscillators play an important role in the functioning of a wide range of electronic systems. Pin Configurable or Selectable Oscillators (533BA000270DGR) allow users to set the output frequency of an oscillation signal that can be configured via pins using an MCU or external chip. Pin configurable/selectable oscillators provide users with both precision and freedom of frequency selection, something unavailable in traditional oscillators such as resonators and crystals.

Traditional oscillators rely on the resonance of conductors and other materials to generate an oscillation signal that is then amplified and output. Pin configurable/selectable oscillators take a different approach, operating on the basis of Self-oscillating Digital Frequency Locked Loop or Self-oscillating Delta- Sigma Modulator (DCFLL).

The DCFLL, also referred to as the Free-Running Injection-Locked Frequency Divider (FRILFD), is a type of device for generating an oscillation signal by means of intrinsic digital signal processing. It is based on a feedback mechanism between an input signal, the Modulo-counter, and a digital-controlled oscillator (DCO), also known as a voltage-controlled oscillator (VCO). This oscillation signal is then amplified, filtered, and output by the device.

In a pin configurable/selectable oscillator, such as the 533BA000270DGR, the user is able to configure the desired output frequency by connecting the pins of the device to an MCU or external chips, such as a Selectable Oscillator Programmer (SOP). The SOP is then able to send the appropriate configuration signals to the pins of the oscillator, setting the frequency to anything from 10MHz to 66MHz.

The 533BA000270DGR allows for an output frequency of 2.8MHz – 66Mhz, a frequency stability of +-20ppm, and an operating voltage range of 2.4VDC to 3.6VDC. This oscillator is suitable for a wide range of applications, from telecommunications, audio and video equipment, automotive electronics and automotive products.

The main advantages of pin configurable/selectable oscillators include: increased precision and accuracy, as well as wide range of frequencies. The programme frequencies are more accurate in comparison to traditional oscillators, increasing the accuracy of the oscillations and allowing for better performance. Furthermore, the wider selection of frequencies available with pin configurable/selectable oscillators allows for greater flexibility in applications.

In conclusion, pin configurable/selectable oscillators such as the 533BA000270DGR are gaining in popularity due to the increased precision, selection of frequencies and increased accuracy available. They are suitable for a range of applications, from telecommunications and audio/video equipment, to automotive products.
