Product details

Its 1.8V to 3.3V supply range lets it run directly from a 1.8V MCU rail or a 3.3V system bus without an intermediate regulator — one BOM line covers both voltage domains.

Standby power-down and low active current

Active current is 6.3 mA max at 12 MHz, which is typical for a MEMS oscillator at this frequency and keeps the thermal contribution in the 3.2 x 2.5 mm package manageable.

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits the standard 3.2 x 2.5 mm crystal oscillator footprint used across many MCU reference designs. Surface-mount assembly with a no-lead package means the solder joints are under the body — ensure the PCB land pattern matches the recommended layout in the datasheet to avoid tombstoning during reflow.

Frequently asked questions

What is the exact frequency of the DSC1001CI2-012.0000?

The exact output frequency is 12 MHz. The part number suffix -012.0000 encodes this frequency directly.

What supply voltage range does the DSC1001CI2-012.0000 support?

It operates from 1.8V to 3.3V, covering the three most common digital logic rails without needing an external regulator.

Is the DSC1001CI2-012.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which qualifies it for automotive applications including under-hood and cabin electronics.

Does the DSC1001CI2-012.0000 have a standby power-down feature?

Yes, the function is Standby (Power Down). When disabled, the supply current drops to 15 µA max, allowing the oscillator to be gated off during system sleep without removing power.

What package does the DSC1001CI2-012.0000 come in?

It is supplied in a 4-SMD, No Lead package with dimensions 3.20 mm x 2.50 mm and a seated height of 0.90 mm. The package is surface-mount and uses a standard 3.2 x 2.5 mm footprint.
