The MEMS resonator replaces a quartz crystal, giving better shock and vibration tolerance and a faster start-up time compared to a traditional crystal oscillator. ## Supply voltage and standby power-down Supply voltage range is 1.8V to 3.3V, covering the common digital core and I/O rails — no external level translator needed when the oscillator feeds a 1.8V or 3.3V clock input. A standby (power-down) function drops the supply current to 15 µA max when the enable pin is de-asserted, letting the system gate the oscillator off during sleep modes without a separate load switch. Active current draw is 8.7 mA max at 125 MHz — the MEMS architecture keeps power low even at this frequency, which matters for thermally constrained automotive ECUs. ## Package and board layout notes Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad on the underside should be soldered to a ground-plane thermal land for best thermal and electrical performance. Surface-mount assembly with standard reflow profiles; the MEMS die inside is less sensitive to reflow temperature gradients than quartz, but follow the recommended solder-land pattern in the datasheet. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001AI2-125.0000 MEMS Oscillator 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1001AI2-125.0000 XO (Standard) MEMS oscillator, 125 MHz CMOS output, ±25 ppm stability, AEC-Q100, -40°C to 85°C.
