Product details

The DSC1121BE5-025.0000 is an active-production MEMS-based XO (Standard) from Microchip Technology, delivering a 25 MHz CMOS output with ±10 ppm frequency stability across -20°C to 70°C. Its 2.25V to 3.6V supply range covers 2.5V and 3.3V logic rails directly, eliminating a dedicated LDO in many designs.

Package and footprint – 5.0×3.2 mm 6-SMD no-lead

Housed in a 6-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the DSC1121BE5-025.0000 fits standard oscillator footprints used by quartz and MEMS devices alike.

Frequently asked questions

Is DSC1121BE5-025.0000 AEC-Q100 qualified?

Yes, this oscillator carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests including temperature cycling and ESD immunity. It is suitable for under-hood and cabin electronics where the ambient temperature stays within -20°C to 70°C.

Can DSC1121BE5-025.0000 replace a standard quartz oscillator?

Yes, the DSC1121BE5-025.0000 is a MEMS-based XO that is footprint-compatible with many 5.0×3.2 mm quartz oscillators. It offers ±10 ppm frequency stability and a wide 2.25V–3.6V supply range, making it a drop-in replacement for 25 MHz CMOS quartz oscillators in most designs. The MEMS resonator is inherently more shock and vibration tolerant than quartz.

Is DSC1121BE5-025.0000 compatible with standard 3.3V logic?

Yes, the 2.25V–3.6V supply range includes 3.3V, and the CMOS output swings rail-to-rail, so it interfaces directly with 3.3V logic families.
