Product details

What this MEMS oscillator does on the board

It operates from a 1.8V to 3.3V supply rail, drawing 6.3 mA max at full speed, and drops to 15 µA in standby mode via the power-down pin — a sleep-mode enabler for battery-backed automotive modules.

It fits under-hood and cabin-domain ECUs where a commercial-grade crystal would risk drift or failure.

Product status is Active.

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2x2.5 mm oscillator footprint that matches many quartz and MEMS drop-in replacements.

Frequently asked questions

Is DSC1001CI2-025.0012T AEC-Q100 certified?

Yes, it carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. Suitable for under-hood and chassis-domain applications.

How does this MEMS oscillator compare to a standard quartz oscillator?

The MEMS resonator offers better shock and vibration tolerance than a quartz crystal, and the ±25 ppm stability is comparable to a basic quartz XO. The standby function with 15 µA disable current is a power-saving feature not always available on quartz oscillators.
