The MEMS resonator inherently withstands higher shock and vibration than quartz, a practical advantage in engine bay, transmission, and suspension control modules. ## Supply range and output control Wide supply range of 2.25V to 3.6V lets the oscillator run directly from a 2.5V or 3.3V rail without an extra LDO — simplifies the power tree in mixed-voltage automotive designs. The Enable/Disable function gates the output, dropping the max supply current from 35 mA to 22 mA — useful for power-cycled sensor nodes or test-mode isolation. Surface-mount assembly with standard reflow profiles; no special handling beyond MSL level — the MEMS die is sealed in the package, so no moisture sensitivity beyond typical SMD components. The DSC1121 family shares the same footprint across frequency variants, so a 10 MHz sibling (e.g., DSC1121CI2-010.0000) would be a direct drop-in if the temp grade differs.","metaTitle":"DSC1121AI2-010.0000 MEMS Oscillator 10 MHz AEC-Q100 -","metaDescription":"DSC1121AI2-010.0000 XO (Standard) 10 MHz CMOS MEMS oscillator, AEC-Q100 qualified, -40°C to +85°C, ±25 ppm stability, Enable/Disable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"10 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DSC1121AI2-010.0000 have an enable/disable function?","answer":"Yes, the Enable/Disable function gates the CMOS output.
