That means one oscillator replaces what would otherwise take two or three quartz cans plus a clock buffer on a mixed-speed bus like an FPGA with separate Ethernet and USB domains. The wide supply range of 2.25 V to 3.6 V lets it run directly from a 2.5 V or 3.3 V rail without an intermediate LDO — one less component in the power tree. This is a current catalog part, safe to design into a new BOM or to replenish an existing line without worrying about a sudden EOL notice. The 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height) needs a thermal via array under the paddle for best heat transfer — the datasheet's recommended footprint shows a 3×3 via grid.","metaTitle":"DSC400-0111Q0117KE2 MEMS XO – 16.64/33/25 MHz, LVCMOS","metaDescription":"Microchip DSC400-0111Q0117KE2: MEMS-based XO, 3 outputs (16.64/33/25 MHz), LVCMOS, ±25 ppm, 2.25-3.6V, -20 to 70°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","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":"±25ppm","Frequency - Output 1":"16.64MHz","Frequency - Output 2":"33MHz","Frequency - Output 3":"25MHz","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8737840499b4324a60ff65ab9973077c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC400-0111Q0117KE2 or get a quote?","answer":"This is an active Microchip catalog part. We source it through independent distribution and quote to order against your BOM quantity — no minimums, no shelf-stock claims. Submit an RFQ for current pricing and lead time; the 20-VFQFN package is available in tube packaging per the listed spec."},{"question":"Is the DSC400-0111Q0117KE2 a drop-in replacement for a quartz crystal oscillator?","answer":"It is a direct functional replacement for a standard XO with LVCMOS outputs at those three frequencies — same supply range, same output logic levels. The MEMS die means it starts up faster (typically <5 ms) and handles vibration better than a quartz can. Pin compatibility depends on the specific quartz XO footprint; the DSC400 uses a 20-VFQFN with exposed pad, so verify the pad layout against your existing oscillator's package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0111Q0117KE2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0111Q0117KE2 when reusing this data.
