Product details

MEMS oscillator with ±25 ppm stability

Supply voltage and output control

Operating from a 2.25V to 3.6V supply, this oscillator spans 2.5V, 3.0V, and 3.3V logic rails without needing a separate LDO — one BOM line covers multiple voltage domains.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint matches industry-standard 7x5 mm oscillator pads — a direct drop-in for existing layouts using that form factor.

Frequently asked questions

Does DSC1121AI2-012.2880T have an enable/disable function?

Yes, it includes an Enable/Disable pin that places the output in high-impedance state when pulled low, reducing supply current.
