The MEMS resonator provides inherent shock and vibration immunity compared to quartz, reducing phase-noise degradation in high-g environments such as engine control units, ADAS cameras, and industrial motor drives. ## Supply voltage flexibility and enable/disable function Operating from 2.25V to 3.6V, the oscillator covers 2.5V and 3.3V logic rails without an external regulator — the wide input range simplifies BOM consolidation across multi-rail designs.","metaTitle":"DSC1121AM1-100.0000T MEMS Oscillator – 100 MHz, CMOS","metaDescription":"Microchip DSC1121AM1-100.0000T XO (Standard) MEMS oscillator, 100 MHz CMOS output, ±50 ppm stability, AEC-Q100 qualified, -55°C to 125°C.

The supply voltage range of 2.25V to 3.6V covers 3.3V rails directly. The CMOS output swings rail-to-rail, so it interfaces with 3.3V logic families without level translation."},{"question":"Can the DSC1121AM1-100.0000T replace a standard quartz oscillator in an existing design?","answer":"Functionally yes — it is a drop-in XO replacement with the same 100 MHz CMOS output and 6-SMD footprint (7.00mm x 5.00mm). However, the MEMS resonator has different phase-noise characteristics than quartz; verify jitter margins in PLL-based clock trees.
