Product details

Supply range and power gating

The 2.25V to 3.6V supply range lets you run the same oscillator from a 2.5V or 3.3V rail without an extra LDO — one less component on the BOM.

Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm x 0.90 mm, this oscillator fits tight PCB layouts common in automotive ECUs and portable instrumentation. Surface-mount assembly with a standard reflow profile — no special handling beyond normal SMD practice.

If a future EOL occurs, the same series with a different frequency or stability grade would be the natural migration path.

Frequently asked questions

Does DSC1121CI2-014.7456 have an enable/disable function?

Yes. The Enable/Disable pin lets you shut off the output, reducing supply current from 35 mA max to 22 mA max.

Is DSC1121CI2-014.7456 AEC-Q100 qualified?

Yes. It carries AEC-Q100 automotive qualification, meaning it has passed the reliability stress tests required for automotive-grade electronics.
