Product details

20 MHz MEMS oscillator with ±25 ppm stability

Operating from 2.25V to 3.6V, the oscillator can be powered directly from a 2.5V or 3.3V rail without an external regulator, simplifying the power tree.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that aligns with common oscillator land patterns. Surface-mount assembly; the exposed pad aids thermal conduction to the PCB, though the 35 mA max draw keeps self-heating low.

Frequently asked questions

Can the DSC1101AI2-020.0000 replace a quartz crystal oscillator?

Yes — as a MEMS-based XO, it is a drop-in replacement for a standard quartz oscillator in the same 6-SMD footprint, provided the supply voltage (2.25V–3.6V) and output type (CMOS) match the application. The MEMS version offers faster startup and better shock tolerance.
