That replaces four discrete crystal oscillators on the BOM, freeing board area and reducing procurement line items. ## Supply and temperature fit for industrial designs The wide supply range of 2.25 V to 3.6 V lets this oscillator run directly off a 2.5 V or 3.3 V rail without an extra LDO. ## Package footprint and reflow considerations The 20-VFQFN with exposed pad measures 5.00 mm x 3.20 mm and sits 0.90 mm tall.","metaTitle":"DSC400-1111Q0081KI1 MEMS XO - Microchip, Quad LVCMOS Output","metaDescription":"Active-production quad-output MEMS oscillator from Microchip. 27/50/25/12 MHz LVCMOS, ±50ppm, -40°C to 85°C, 2.25-3.6V.","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":"27MHz","Frequency - Output 2":"50MHz","Frequency - Output 3":"25MHz","Frequency - Output 4":"12MHz","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d80e8a58f92db67961f48a0d6fa6d4d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-1111Q0081KI1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-1111Q0081KI1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-1111Q0081KI1 when reusing this data.
