What this MEMS oscillator does on your board
The MEMS resonator is sealed inside the package, so it resists shock and vibration better than a quartz crystal in the same 3.2 mm × 2.5 mm footprint. It runs from a single 1.8 V to 3.3 V supply, which means one part number covers both 1.8 V and 3.3 V logic domains — useful when a board has mixed-voltage interfaces and you want to avoid stocking two oscillators.
Automotive-grade timing for cabin and infotainment
The MEMS construction also survives the vibration profile of an automotive environment better than a quartz crystal. The ±25 ppm frequency stability is tight enough for a 24.576 MHz reference clock feeding an audio codec (common sample-rate clock) or a USB controller — no external trimming required.
Microchip lists the DSC1001CE2-024.5760 as Active.
