Product details

Supply voltage spans 1.8 V to 3.3 V, covering common digital core and I/O rails without an external regulator, and the Enable/Disable function lets the system shut down the oscillator to 15 µA max standby current.

MEMS vs quartz — why the ±10 ppm holds

Unlike a quartz crystal that ages and shifts frequency with mechanical shock, the MEMS resonator in the DSC1001 series maintains its ±10 ppm stability over temperature and lifetime without a separate trim capacitor or external load capacitance. The 7.2 mA max supply current at 27 MHz is comparable to a standard quartz oscillator, but the MEMS construction eliminates the start-up reliability issues quartz can exhibit at cold temperatures — a known failure mode in automotive cold-crank conditions.

The 4-SMD, No Lead Exposed Pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm, fitting standard 7×5 mm oscillator footprints without board layout changes.

Frequently asked questions

Is the DSC1001AI5-027.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability testing for temperature, ESD, and latch-up — suitable for under-hood and chassis-domain applications.

How does the DSC1001AI5-027.0000 compare to a standard 27 MHz quartz oscillator?

The MEMS resonator eliminates quartz aging and shock sensitivity, maintaining ±10 ppm stability without external load capacitors. It is a drop-in replacement for standard 27 MHz XOs in vibration-prone or automotive environments, with the same 7.2 mA max supply current.
