Additional Details
The SF2092E operates at a specific frequency and is available in a standard ceramic package. Its frequency stability is typically specified in parts per million (ppm) over a certain temperature range. The device requires external load capacitors for proper operation, and the values of these capacitors should be chosen according to the manufacturer's recommendations to achieve the desired frequency accuracy and stability. Proper layout techniques should be followed to minimize noise and ensure stable oscillation. The device is also RoHS compliant, making it suitable for environmentally conscious applications. It is important to consult the datasheet for the exact operating frequency, tolerance, and recommended load capacitance values. While ceramic resonators offer a cost-effective solution, quartz crystals are generally preferred for applications requiring higher frequency accuracy and stability.
