That replaces up to four quartz oscillators on the board, freeing layout area and cutting the BOM count. ## Supply rail flexibility and temperature range Runs from 2.25 V to 3.6 V, so it sits comfortably on either a 2.5 V or 3.3 V rail without a separate LDO. VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height. The pad is also the only ground return for the MEMS die, so a poor solder joint under the pad can cause frequency jitter. Will it survive hot air? Yes — the VFQFN is a standard reflow package. The exposed pad wets well if the stencil aperture is sized for 50-60% coverage. No hidden thermal mass traps — the part reflows cleanly at a standard SAC305 profile. The base product number DSC400 covers a family of multi-output MEMS oscillators; if the frequency set changes in a future board spin, a different variant in the same package and pinout may fit without a layout change.","metaTitle":"DSC400-1111Q0091KE1T MEMS XO – 4-Output LVCMOS Oscillator","metaDescription":"DSC400-1111Q0091KE1T MEMS XO from Microchip: 12/24/48/14.25 MHz LVCMOS outputs, 2.25-3.6V supply, ±50 ppm stability, -20°C to +70°C.","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":"24MHz","Frequency - Output 3":"48MHz","Frequency - Output 4":"14.25MHz","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/17b6406e65b9416d394307ca5caa9e62.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the DSC400-1111Q0091KE1T support spread-spectrum clocking?","answer":"No. The evidence lists only a standard XO (Standard) type with Enable/Disable function.
