The MEMS resonator eliminates quartz crystal startup issues and offers better shock/vibration tolerance, which is why this part carries AEC-Q100 qualification. ## Supply voltage tolerance and frequency stability The 1.8V to 3.3V supply range means a single oscillator can serve both 1.8V-core MCUs and 3.3V peripheral buses without a voltage translator — the output swing tracks the supply rail. The ±50 ppm absolute pull range (APR) covers temperature drift and aging, keeping the clock within tolerance for protocols like 100BASE-TX or USB 2.0 without external trimming. ## Package footprint and layout consideration The 4-VDFN package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that suits space-constrained PCBs (ADAS cameras, sensor modules). The MEMS die inside is sensitive to mechanical vibration; the datasheet recommends mounting the oscillator away from board edges and high-vibration areas (relays, solenoids) to avoid frequency modulation.","metaTitle":"DSC1001DI1-116.6666 MEMS XO – 116.6666 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001DI1-116.6666 MEMS oscillator: 116.6666 MHz, CMOS output, 1.8V–3.3V supply, ±50 ppm APR, AEC-Q100, -40°C to 85°C.
