Pin Configurable/Selectable Oscillators are a type of oscillator that can be configured or selected via the pins on the device itself. The 552CM000109DGR oscillator is an example of such a device. It is a versatile quartz-based oscillator that offers both precision and reliability for crystal oscillators and ceramic resonators. In this article, we will discuss the application field and working principle of the 552CM000109DGR.The 552CM000109DGR is designed for applications such as frequency selection by pin-strapping, factory set frequency variation, frequency trimming for mass tuning, frequency calibration for end-users, and temperature compensation for automotive applications. Its operating condition is a wide operating temperature range of -40 to +85°C. It also very low-power consumption of 350µW @ 0.5V. In addition, the 552CM000109DGR has a wide range of frequency options available, with a nominal frequency range of 0.32MHz to 70MHz (0.5 x f-out). For maximum design flexibility, the 552CM000109DGR can also be trimmed up to ±75kHz with a minimum inductance load.The 552CM000109DGR works on the principle of crystal control. An external crystal can be connected to the oscillator through two optimized pads mounted on the underside of the device. This will take the form of a parallel resonance circuit. This crystal is then controlled by the oscillator chip, which uses a proprietary method of stabilization to generate the desired output frequency. In addition to the crystal, the oscillator also requires a few passive components in order to complete the oscillator circuit. These components are typically a few resistors, capacitors, and an inductor.Once the oscillator is operational, the frequency can be pin-strapped to adjust the frequency and make it stable. This technique is a reliable and cost-effective solution for tuning the crystal oscillator for various applications. The frequency variation is typically ±50ppm at 25°C, ±75ppm over a -40 to +85°C range and < ±10ppm/or-bit over a wide range of operating supply voltages.In summary, the 552CM000109DGR is a pin configurable/selectable quartz-based oscillator designed for a wide variety of applications. Its main application is frequency selection by pin-strapping, factory set frequency variation, frequency trimming for mass tuning, frequency calibration for end-users, and temperature compensation for automotive applications. The device utilizes an external crystal and a few passive components to generate a stable output frequency that can be adjusted by pin-strapping. Its wide frequency range, low-power consumption, and wide operating range make it an ideal solution for many applications.
