It operates from a 2.25 V to 3.6 V supply, so it can be powered directly from a 2.5 V or 3.3 V rail without an intermediate regulator — a clean clock starts from a clean rail, and the wide input range keeps the phase noise floor independent of rail tolerance. 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 DSC400-0111Q0029KE2 fits tight PCB real estate but requires a thermal via array under the exposed pad to conduct heat to the ground plane — the datasheet layout recommendation should be followed for best thermal and electrical performance. The LVCMOS outputs are single-ended, so the trace routing from each output to its load must be impedance-controlled (typically 50 Ω) and length-matched within the group to minimize skew between the 11.2896 MHz copies.","metaTitle":"DSC400-0111Q0029KE2 XO MEMS Oscillator – Microchip","metaDescription":"DSC400-0111Q0029KE2: MEMS XO, 4-output LVCMOS, 12.288/11.2896 MHz, ±25 ppm, 2.25-3.6 V, 20-VFQFN, Active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"LVCMOS","Series":"DSC400","Function":"Enable/Disable","Packaging":"Tube","Part Status":"Active","Manufacturer":"Microchip Technology","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","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":"11.2896MHz","Frequency - Output 3":"11.2896MHz","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/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC400-0111Q0029KE2 or check availability?","answer":"The part is Active per Microchip.
