Product details

22.5792 MHz MEMS oscillator with wide supply tolerance

The DSC1121AI5-022.5792 is a standard XO (Standard) MEMS oscillator from Microchip's DSC1121 series, delivering a 22.5792 MHz CMOS output. Its supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without a separate regulator — the internal LDO handles the range.

Industrial temperature grade and enable/disable function

Max supply current is 35mA when enabled, dropping to 22mA when disabled.

Product status is Active.

Housed in a 6-VDFN exposed pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm.

Frequently asked questions

Does the DSC1121AI5-022.5792 have an enable/disable function?

Yes, the function is Enable/Disable. Pin 1 controls the output: a logic high enables the clock, logic low disables it. Max supply current when disabled is 22mA.

Is the DSC1121AI5-022.5792 compatible with 3.3V logic?

Yes. The 2.25V to 3.6V supply range includes 3.3V, and the CMOS output swings rail-to-rail, so it drives 3.3V logic inputs directly.
