Sourced per RFQ; availability confirmed at quote time. ## Frequency stability and output type for signal integrity ±50 ppm frequency stability over the full industrial temperature range keeps the clock edge within the receiver's timing budget for 100 MHz HCSL — the differential swing and common-mode voltage match the PCIe and SATA reference-clock specs without external termination resistors.","metaTitle":"DSC400-0404Q0058KI1T XO Oscillator – Dual 100 MHz HCSL","metaDescription":"DSC400-0404Q0058KI1T from Microchip Technology: MEMS-based XO, dual 100 MHz HCSL outputs, 2.25V-3.6V supply, ±50ppm stability, -40°C to 85°C.","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":"HCSL","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":"100MHz","Frequency - Output 2":"-","Frequency - Output 3":"100MHz","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":"What is the exact output frequency and type of DSC400-0404Q0058KI1T?","answer":"The device provides two 100 MHz HCSL outputs.
