Surface-mount reflow follows standard JEDEC profiles; the no-lead construction reduces parasitic inductance compared to a gull-wing package. The Enable/Disable pin should be pulled high or low externally — leaving it floating risks an indeterminate output state.","metaTitle":"DSC1121NM1-025.0000T MEMS Oscillator – 25 MHz, CMOS","metaDescription":"Microchip DSC1121NM1-025.0000T: 25 MHz XO, CMOS output, ±50 ppm stability, -55°C to +125°C, AEC-Q100 qualified, 6-SMD package.

The MEMS resonator offers better vibration and shock resistance than quartz, but the frequency stability (±50 ppm,) is comparable to a standard quartz XO. Verify the supply voltage and Enable/Disable logic polarity match your existing design."},{"question":"What is the difference between MEMS and quartz oscillators?","answer":"MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They are generally more resistant to vibration and mechanical shock, have faster start-up times, and are less sensitive to supply-voltage noise. The DSC1121NM1-025.0000T's MEMS base resonator delivers the same ±50 ppm stability as a typical quartz XO but with improved ruggedness across the -55°C to +125°C range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121NM1-025.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121NM1-025.0000T when reusing this data.
