This dual-frequency capability lets a single oscillator replace two discrete crystal oscillators on the board, saving footprint and reducing BOM line count. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator. ## Package and layout considerations for the 20-QFN Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.50 mm pitch QFN demands careful solder-paste stencil design to avoid bridging; a 4-mil stencil with 1:1 aperture-to-land ratio is a common starting point. No special high-speed layout rules beyond standard 50-ohm trace impedance for the LVCMOS outputs if the trace length exceeds 1 inch.","metaTitle":"DSC400-0101Q0114KE1T XO Oscillator – 12 MHz & 12.288 MHz","metaDescription":"Microchip DSC400-0101Q0114KE1T dual-output MEMS XO: 12 MHz & 12.288 MHz, ±50 ppm stability, 2.25-3.6 V, enable/disable, 20-QFN.","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":"±50ppm","Frequency - Output 1":"12MHz","Frequency - Output 2":"12.288MHz","Frequency - Output 3":"-","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/7d42f93cfc487ade1aadfbf79746fe39.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the two output frequencies of the DSC400-0101Q0114KE1T?","answer":"Output 1 is 12 MHz; Output 2 is 12.288 MHz.

It is a drop-in functional replacement for a dual-output quartz XO in the same package and with the same supply voltage, but the MEMS resonator has different aging and vibration characteristics — review the Microchip application note for MEMS timing if the board sees high mechanical shock or wide temperature swings beyond the rated -20°C to +70°C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0101Q0114KE1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0101Q0114KE1T when reusing this data.
