Product status is Active — still supported for new designs and production. The MEMS resonator construction typically means shorter manufacturing lead times than quartz-based oscillators, which helps when filling a BOM line on a tight schedule.","metaTitle":"DSC1121CM1-040.0000 – Microchip MEMS XO, 40 MHz, CMOS","metaDescription":"DSC1121CM1-040.0000 from Microchip: 40 MHz XO, CMOS output, ±50 ppm stability, 2.25V–3.6V supply, -55°C to 125°C range.

The DSC1121 series shares the same MEMS resonator, CMOS output, and package footprint. The difference is typically in the output drive strength or enable logic — confirm the specific ordering code suffix against the datasheet."},{"question":"Is DSC1121CM1-040.0000 compatible with 2.5V logic?","answer":"Yes. The supply voltage range is 2.25V to 3.6V, which covers both 2.5V and 3.3V rails. The CMOS output swings rail-to-rail, so it directly drives 2.5V logic inputs without a level shifter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CM1-040.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CM1-040.0000 when reusing this data.
