Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without a separate regulator. Frequency stability is rated at ±25 ppm over the full -40°C to +85°C industrial temperature range — tight enough for a 100BASE-TX Ethernet reference clock, where the total jitter budget typically allows ±50 ppm including the PHY's own drift. Product status is Active — no last-time-buy, no NRND flag. Package dimensions are 5.00 mm x 3.20 mm with a 0.90 mm height — the 20-VFQFN Exposed Pad requires a thermal via array under the pad for proper heat dissipation, especially when all four outputs are driving long traces.","metaTitle":"DSC400-0111Q0116KI2T MEMS XO – 4-output LVCMOS oscillator","metaDescription":"Microchip DSC400-0111Q0116KI2T MEMS XO (Standard) with ±25 ppm stability, 2.25V–3.6V supply, four LVCMOS outputs (12.288, 14.7456, 11.2896 MHz).","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":"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":"±25ppm","Frequency - Output 1":"12.288MHz","Frequency - Output 2":"14.7456MHz","Frequency - Output 3":"11.2896MHz","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/41a2dcc1573e66d7260ef0cfef766dd1.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0111Q0116KI2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0111Q0116KI2T when reusing this data.
