Product details

18 MHz MEMS oscillator with AEC-Q100 qualification

Rated AEC-Q100, this part is qualified for automotive-grade applications — the MEMS resonator is inherently more shock and vibration tolerant than a quartz crystal, which matters for under-hood or chassis-mounted ECUs.

Supply voltage flexibility and standby power-down

Operates from a single 1.8V to 3.3V supply rail, so the same ordering code works across 1.8V, 2.5V, or 3.3V logic domains without a separate regulator or level translator. A Standby (Power Down) function drops the supply current to 15µA max when disabled — useful for battery-backed modules that need to preserve charge during sleep intervals while keeping the oscillator available for wake-up.

Active production, quoted to order

The DSC1001 series is a current production family, suitable for both new designs and ongoing BOM replenishment.

Frequently asked questions

Is DSC1001DI2-018.0000 AEC-Q100 qualified?

Yes — it carries an AEC-Q100 rating, making it suitable for automotive-grade designs where the oscillator must meet the reliability stress and temperature requirements of the standard.

What does the Standby (Power Down) function do on this oscillator?

When the standby pin is asserted, the output is disabled and the supply current drops to 15µA max, allowing the system to conserve power during sleep modes while keeping the oscillator ready for a fast wake-up.

Can DSC1001DI2-018.0000 replace a quartz oscillator in an existing design?

It is a MEMS-based oscillator with the same 4-SMD no-lead footprint as many quartz oscillators. The key difference is the MEMS resonator's higher shock/vibration tolerance and the ±25ppm stability over temperature. Verify the supply voltage range (1.8V-3.3V) and output type (CMOS) match your design before substituting.
