12 MHz MEMS oscillator – why a ±10 ppm stability band matters
The 6-VDFN exposed pad package is a common oscillator footprint — the thermal pad underneath aids heat dissipation and provides a low-impedance ground return for the output buffer.

Frequently asked questions
What is the frequency of the DSC1121AE5-012.0000?
The oscillator outputs a 12 MHz CMOS clock signal.
What is the closest pin-compatible alternative to the DSC1121AE5-012.0000?
Microchip offers the DSC1121 series in multiple frequency and stability variants sharing the same 6-VDFN footprint and pinout — the base product number DSC1121 covers the family. For a different frequency or tighter stability, another DSC1121 variant with the same package and supply range is the natural drop-in.
