Using a MEMS resonator instead of a quartz crystal, the part delivers ±25 ppm frequency stability across the full -40 to +85°C industrial temperature range — no TCXO needed for most outdoor or factory-floor applications. The 2.25 V to 3.6 V supply range covers common logic rails without a dedicated regulator, and it keeps running through supply dips that would stop a narrower-Vdd oscillator.","metaTitle":"DSC400-0331Q0026KI2 MEMS Oscillator – 25 MHz + 2×125 MHz","metaDescription":"Microchip DSC400-0331Q0026KI2 XO (Standard) MEMS oscillator.
