That means one oscillator footprint and one supply rail doing the job of four discrete XOs — a direct BOM consolidation play for boards that need multiple reference clocks. Outputs are configurable as LVCMOS or LVDS, so the same part can drive a SerDes reference on one lane and a logic clock on another without a level translator. This holds the timing margin for 1000BASE-T, PCIe Gen 2, or USB 3.0 PHY reference clocks even when the board ambient hits 85 °C in a sealed enclosure. The MEMS resonator avoids the aging and shock sensitivity of a quartz crystal — the stability spec is maintained over the device lifetime without a calibration cycle. Supply voltage spans 2.25 V to 3.6 V, so the oscillator runs directly from a 2.5 V or 3.3 V rail without a dedicated LDO. The wide tolerance also absorbs ripple from a noisy bus without losing lock. The 20-VFQFN with exposed pad measures 5.00 mm x 3.20 mm, 0.90 mm tall — a standard quad-flat-pack footprint that reflows with a typical JEDEC profile and does not require via-in-pad unless the thermal pad demands it.","metaTitle":"DSC400-3133Q0080KI2 MEMS XO – Quad Output, ±25 ppm","metaDescription":"Microchip DSC400-3133Q0080KI2 quad-output MEMS oscillator: 148.35/27/25/148.35 MHz, 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":"Tube","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":"148.35MHz","Frequency - Output 2":"27MHz","Frequency - Output 3":"25MHz","Frequency - Output 4":"148.35MHz","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/c64eef9c3ba4d5bb2428f41e8204f955.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency stability of the DSC400-3133Q0080KI2?","answer":"±25 ppm over the full -40 to +85 °C operating range.
