The DSC6001JE3B-040K000T: This is a 40 kHz MEMS-based XO with CMOS output, rated AEC-Q100 — that means it is qualified to automotive stress and reliability standards, not just industrial-grade parts repackaged for a car. The 1.71V to 3.63V supply range lets it run off a 1.8V or 3.3V rail without a level translator — one fewer part on the BOM. Frequency stability is ±20 ppm, tight enough for CAN or LIN wake-up timers where drift matters over temperature.
Package, pinout, and enable/disable control
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — a compact footprint for space-constrained ECU or sensor module PCBs. Surface-mount assembly — no through-hole rework needed; standard reflow profiles for the VLGA land pattern.
