Each output can be configured as LVCMOS or LVDS, giving the designer flexibility to drive both single-ended and differential clock domains from the same device without an external fanout buffer. It is a current production part suitable for new designs. ## Package and layout – 20-VFQFN with exposed pad The 20-VFQFN Exposed Pad package (5.00 mm × 3.20 mm, 0.90 mm height) requires a thermal via array under the center pad to achieve the rated thermal performance. The pad also serves as the primary ground return for the MEMS core. Supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails commonly found in FPGA and SoC clock trees. No external LDO needed if the rail is within this window.","metaTitle":"DSC400-3331Q0098KI2T MEMS XO – 12 MHz + 3×50 MHz, ±25 ppm","metaDescription":"Microchip DSC400-3331Q0098KI2T quad-output MEMS oscillator: 12 MHz + 50 MHz ×3, LVCMOS/LVDS, ±25 ppm, -40 to 85°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":"LVCMOS, 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":"±25ppm","Frequency - Output 1":"12MHz","Frequency - Output 2":"50MHz","Frequency - Output 3":"50MHz","Frequency - Output 4":"50MHz","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/940b3d17f31637bed1ffa04ca5c84ddf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC400-3331Q0098KI2T or check availability?","answer":"The DSC400-3331Q0098KI2T is an active Microchip production part.
