The MEMS resonator eliminates quartz start-up variability and shock sensitivity, making this oscillator a drop-in replacement for standard crystal oscillators in designs that already accept LVDS levels. The 2.25V to 3.6V supply range means the same part runs on a 2.5V or 3.3V rail without a separate level translator – the LVDS output common-mode voltage tracks the supply, so the receiving FPGA or SerDes input sees a valid differential swing across the full range. ## Enable/disable function and package footprint The 20-VFQFN with exposed pad (5.00mm x 3.20mm, 0.90mm height) requires a thermal pad on the PCB for heat sinking; the 0.50mm pitch pads demand careful fan-out but keep the footprint smaller than a comparable 14-pin SOIC oscillator bank.","metaTitle":"DSC400-3333Q0001KI1T MEMS XO – LVDS","metaDescription":"Microchip DSC400-3333Q0001KI1T quad-output MEMS oscillator, LVDS, 2.25-3.6V, -40°C to 85°C, ±50ppm stability, 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":"LVDS","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":"25MHz, 50MHz, 125MHz, 150MHz","Frequency - Output 2":"100MHz, 156.25MHz","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/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC400-3333Q0001KI1T and check availability?","answer":"The DSC400-3333Q0001KI1T is an active Microchip part supplied on tape and reel.

Submit an RFQ for current pricing and lead time – no stock-holding claim is made here."},{"question":"What is the exact frequency combination of the DSC400-3333Q0001KI1T?","answer":"Output bank 1 delivers 25MHz, 50MHz, 125MHz, and 150MHz; output bank 2 delivers 100MHz and 156.25MHz – six frequencies total across four LVDS outputs."},{"question":"Can the DSC400-3333Q0001KI1T replace a standard quartz crystal oscillator?","answer":"Yes, it is a drop-in replacement for standard XOs in designs that accept LVDS levels. The MEMS resonator offers faster start-up and better shock resistance than quartz, but the pinout and supply voltage (2.25V–3.6V) must match the existing footprint."},{"question":"What does the enable/disable pin do on this oscillator?","answer":"The enable/disable pin gates all LVDS outputs without removing the supply.
