Product details

Military temperature range and AEC-Q100 qualification

The oscillator maintains ±10 ppm frequency stability across that span, which means the clock edge stays within tight jitter budgets for high-speed serial links or CAN-FD networks in engine-bay or avionics environments.

Wide supply and MEMS resonator

Input voltage range of 2.25 V to 3.6 V covers both 2.5 V and 3.3 V rails without an extra regulator, simplifying the power tree.

6-SMD no-lead package, 2.50 mm × 2.00 mm body, 0.90 mm seated height. The small footprint suits space-constrained designs; the no-lead construction keeps the parasitic inductance low for clean clock distribution.

Frequently asked questions

Is DSC1121DM5-005.0000 AEC-Q100 qualified?

Yes, the part carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up immunity.
