The ±25 ppm frequency stability holds across the full -40°C to +85°C industrial temperature range, so the clock edges stay within budget for a 25 MHz base or 125 MHz serial link without external trimming. The 20-VFQFN exposed-pad package measures 5.00 mm x 3.20 mm with a 0.90 mm seated height; the exposed pad needs a thermal via array under the centre ground pad to keep the MEMS die within its operating junction temperature.","metaTitle":"DSC400-0331Q0026KI2T MEMS XO – ±25 ppm, 25/125/125 MHz","metaDescription":"Active Microchip DSC400 XO (Standard) with MEMS resonator, ±25 ppm stability, 25/125/125 MHz outputs, LVCMOS/LVDS, enable/disable, -40°C~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":"25MHz","Frequency - Output 2":"125MHz","Frequency - Output 3":"125MHz","Frequency - Output 4":"-","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 DSC400-0331Q0026KI2T or check availability?","answer":"This part is Active and available through independent distribution.
