It replaces the need for multiple discrete crystal oscillators on a board, saving footprint and BOM line count. Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm x 3.20 mm with a 0.90 mm seated height, it fits tight PCB layouts where a single clock IC serves several peripherals. Supply voltage spans 2.25 V to 3.6 V, so the same part can run from a 2.5 V or 3.3 V rail without a separate LDO — one less component on the BOM. ## Active production, no end-of-life notice The Enable/Disable function on the package lets a firmware GPIO gate the outputs — useful for power-saving sleep modes in battery-operated equipment.","metaTitle":"DSC400-0111Q0087KI1 MEMS XO – 4-output LVCMOS","metaDescription":"DSC400-0111Q0087KI1 from Microchip: Active MEMS XO, 4 LVCMOS outputs at 25/24/33.333333 MHz, ±50 ppm stability, 2.25-3.6 V supply, industrial temp.","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","Series":"DSC400","Package":"Tube","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":"25MHz","Frequency - Output 2":"24MHz","Frequency - Output 3":"33.333333MHz","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ac625a807fc2ff16f0820ef2a067324f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC400-0111Q0087KI1 replace a standard crystal oscillator?","answer":"Yes — it is a MEMS-based XO (standard oscillator), not a bare crystal. It outputs a clean LVCMOS clock directly; no external load capacitors or inverter stage are needed. Drop it onto the same 3.3 V or 2.5 V rail and route the output to the clock input of your processor or PHY."},{"question":"Is DSC400-0111Q0087KI1 pin-compatible with other DSC400 series variants?","answer":"The DSC400 family shares the same 20-VFQFN footprint and pinout across frequency-configuration variants. A different order code in the series (same package) will be footprint-compatible, but the output frequencies differ — verify the frequency plan against your BOM before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0111Q0087KI1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0111Q0087KI1 when reusing this data.
