27 MHz MEMS oscillator with ±25 ppm stability
The DSC1001AE2-027.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 27 MHz CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. A wide supply voltage range of 1.8V to 3.3V means this single oscillator can serve designs running on 1.8V, 2.5V, or 3.3V rails without a separate regulator — a BOM simplification for multi-voltage systems. AEC-Q100 qualification extends the application envelope to automotive-grade environments — engine control modules, body controllers, and infotainment clusters where quartz oscillators may fail under shock or vibration.
