With ±50 ppm frequency stability, the part holds timing within 50 parts per million over voltage, temperature, and aging — a standard for 1 GbE and PCIe Gen 1/2 reference clocks. ## Supply voltage and footprint for layout Runs from a 2.25 V to 3.6 V supply, covering 2.5 V and 3.3 V rails without an external LDO — the internal regulator rejects supply ripple from the board's switching converter. The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm, 0.90 mm height) requires a thermal via array under the pad for heat sinking; the LVDS output edge rate benefits from a 100 Ω termination resistor placed within 0.5 inch of the output pins. Microchip Technology is the sole source.","metaTitle":"DSC400-3333Q0001KI1 MEMS XO – LVDS, 6 Freq Outputs, Active","metaDescription":"Microchip DSC400-3333Q0001KI1 XO (Standard) with LVDS output, six combined frequencies: 25/50/125/150 MHz and 100/156.25 MHz.","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":"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":"±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":"What is the exact output frequency configuration of the DSC400-3333Q0001KI1?","answer":"Output 1 provides 25 MHz, 50 MHz, 125 MHz, and 150 MHz simultaneously.
