The 0.90 mm height suits tight card-edge clearance in mezzanine or blade-style boards. ## Active production status and sourcing posture","metaTitle":"DSC400-3331Q0098KI1T MEMS XO Oscillator – Microchip","metaDescription":"Microchip DSC400-3331Q0098KI1T XO (Standard) MEMS oscillator: quad outputs (12 MHz + 3x 50 MHz), LVCMOS/LVDS, ±50 ppm stability, -40°C to +85°C, 20-VFQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVCMOS, LVDS","Series":"DSC400","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC400","Frequency Stability":"±50ppm","Frequency - Output 1":"12MHz","Frequency - Output 2":"50MHz","Frequency - Output 3":"50MHz","Frequency - Output 4":"50MHz","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/940b3d17f31637bed1ffa04ca5c84ddf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-3331Q0098KI1T/alternatives.json"},"ai":{"faq":[{"question":"How can I order the DSC400-3331Q0098KI1T or check availability?","answer":"The DSC400-3331Q0098KI1T is an active Microchip part. Submit an RFQ with your target quantity and delivery window; we source through independent distribution and confirm pricing and lead time per order. No stock-holding claim is made on this page."},{"question":"What are the exact output frequencies of the DSC400-3331Q0098KI1T?","answer":"The device provides four outputs: one at 12 MHz and three at 50 MHz. Each output can be independently configured as LVCMOS or LVDS."},{"question":"Can the DSC400-3331Q0098KI1T replace a quartz crystal oscillator?","answer":"Yes — it is a direct functional replacement for a standard XO (oscillator) in the same footprint, but with MEMS technology. The MEMS resonator eliminates quartz start-up issues and offers better shock/vibration tolerance. Verify the 20-VFQFN footprint matches your existing layout before substitution."},{"question":"Is the DSC400-3331Q0098KI1T suitable for outdoor or industrial environments?","answer":"Yes. The -40°C to +85°C operating temperature range covers outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics. The MEMS construction also resists the vibration and thermal cycling common in those settings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-3331Q0098KI1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-3331Q0098KI1T when reusing this data.
