Supply voltage spans 2.25V to 3.6V, so a single BOM line covers both 2.5V and 3.3V clock domains without a separate supply variant. ## Automotive-grade qualification and package Housed in a 6-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. The no-lead construction eliminates solder-joint fatigue from thermal expansion mismatch on automotive PCBs.","metaTitle":"DSC1121CE1-033.3333T MEMS XO 33.3333 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CE1-033.3333T XO (Standard) MEMS oscillator, 33.3333 MHz CMOS output, ±50 ppm stability, 2.25V-3.6V supply, AEC-Q100 qualified.","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":"33.3333 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121CE1-033.3333T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1121CE1-033.3333T AEC-Q100 qualified?","answer":"Yes, the DSC1121CE1-033.3333T carries AEC-Q100 ratings, meaning it has passed automotive-grade IC qualification including temperature cycling and reliability stress tests."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CE1-033.3333T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CE1-033.3333T when reusing this data.
