This temperature grade is rare for a MEMS oscillator — it covers avionics, satellite, downhole drilling, and engine-bay ECUs where quartz oscillators often suffer activity dips or startup failures at temperature extremes. This matters for any BOM that ships into a vehicle's under-hood or chassis domain — the oscillator won't drift open-loop when the ambient hits 105°C on a summer grade. ## Supply voltage flexibility and disable current The device operates from a 2.25V to 3.6V supply, covering the common 2.5V, 3.0V, and 3.3V logic rails without a separate regulator. ## 6-SMD package and board layout considerations Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.","metaTitle":"DSC1121AM2-033.3330T Microchip MEMS XO, 33.333 MHz, AEC-Q100","metaDescription":"DSC1121AM2-033.3330T: Microchip DSC1121 series MEMS XO, 33.333 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified, -55°C to 125°C.","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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"33.333 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":"-55°C~125°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":"Is the DSC1121AM2-033.3330T AEC-Q100 qualified for automotive use?","answer":"Yes, the Ratings field explicitly lists AEC-Q100."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121AM2-033.3330T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121AM2-033.3330T when reusing this data.
