MEMS oscillators are generally more resistant to vibration and shock, and they typically offer faster start-up times. The trade-off is that quartz can achieve tighter frequency stability in some high-end applications, but the ±50 ppm stability here covers most industrial and communications needs."},{"question":"Can DSC400-0303Q0092KI1T operate at 3.3V supply?","answer":"Yes, the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is well within spec.
