DSC1001CI2-003.8000 MEMS XO – Microchip, 3.8 MHz, CMOS

MEMS oscillator, not a quartz crystal

The DSC1001CI2-003.8000 is a MEMS-based oscillator (XO), not a quartz crystal — it generates a fixed 3.8 MHz clock from a silicon resonator, not a quartz blank.

Automotive-grade timing

Operating temperature spans -40 to 85°C, covering the industrial and passenger-cabin automotive range.

Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint for space-constrained automotive ECUs or sensor modules. Surface-mount, reflow-compatible; no through-hole or manual assembly step.
