Pin configurable/selectable oscillators are a type of enhanced crystal oscillator that allows users to select the output frequency, rise/fall time and often other properties. An example of such an oscillator is the 552BD000972DGR, a frequency-selectable low-skew oscillator from TDK Corporation.The 552BD000972DGR is a low-power oscillator with a frequency range of 8 MHz to 200 MHz and an output frequency range of 122.88/125 MHz, 144.5/146.5 MHz, 147.456/148.541 MHz, 156.25/157.5 MHz, and 158.435/160.664 MHz. It also has a very small package size of 5 mm x 3.2 mm x 0.9 mm, making it ideal for many applications.The key feature of the 552BD000972DGR is its pin configurability and selectability. This type of oscillator allows users to select the frequency, output rise and fall time, power supply voltage, and other parameters. It also offers small footprint, low current and high flexibility.The 552BD000972DGR is suitable for many applications, such as mobile phones, set-top boxes, automotive electronics and other consumer electronics. Additionally, due to its pin configurability and selectability, it is suitable for many high-speed signal integrity applications.The working principle of the 552BD000972DGR is rooted in the traditional crystal oscillator circuit. The crystal resonator, used in the oscillator, operates on the principle of piezoelectric effect: when a voltage is applied across the crystal, it produces a mechanical strain that causes the crystal to vibrate at a very specific frequency. The output frequency of the oscillator is determined by the frequency of the crystal. The frequency of the crystal is selected through pin configurability and selectability, thus allowing the user to select the desired output frequency. The oscillator works in conjunction with an inverting amplifier, which inverts the crystal signal and drives it to the output.The 552BD000972DGR also has built-in ESD protection, as well as integrated temperature and voltage compensation. This ensures that the output frequency is accurate and stable under a wide range of environmental conditions.In conclusion, the 552BD000972DGR is a frequency-selectable low-skew oscillator from TDK Corporation that offers pin configurability and selectability. It is suitable for many applications, such as mobile phones, set-top boxes, automotive electronics and other consumer electronics. Additionally, it has built-in ESD protection, temperature compensation, and voltage compensation, ensuring that the output frequency is accurate and stable under a wide range of environmental conditions.
