Its supply voltage spans 2.25V to 3.6V, so it runs directly from a 2.5V or 3.3V rail without an intermediate LDO — a clean power-tree simplification for mixed-voltage systems. ## Package and thermal layout for the 20-VFQFN Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the DSC400-3333Q0001KE1T requires the centre pad to be soldered to a PCB ground plane for both thermal dissipation and a low-impedance return path — a standard via-in-pad or thermal-via array under the pad keeps the junction temperature within the -20°C to 70°C operating range.","metaTitle":"DSC400-3333Q0001KE1T MEMS Oscillator – 6 LVDS Outputs","metaDescription":"Microchip DSC400-3333Q0001KE1T XO (Standard) MEMS oscillator, LVDS output, six frequencies from 25 to 156.25 MHz, 2.25V–3.6V supply, -20°C to 70°C, 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":"-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":"What output frequencies does the DSC400-3333Q0001KE1T provide?","answer":"It provides six LVDS output frequencies: 25 MHz, 50 MHz, 125 MHz, 150 MHz on one output bank, and 100 MHz, 156.25 MHz on a second bank."},{"question":"Can the DSC400-3333Q0001KE1T run from a 2.5V supply?","answer":"Yes.
