Outputs are configurable as HCSL or LVPECL, covering the common clock standards for PCIe, Ethernet, and FPGA reference inputs without external level translation. Supply range spans 2.25V to 3.6V, so the same part runs on a 2.5V or 3.3V rail — no need for a separate LDO or regulator for the oscillator. The 0.90 mm height fits standard board-to-board spacing constraints.","metaTitle":"DSC400-0244Q0009KE1T MEMS XO – Dual 100 MHz, HCSL/LVPECL","metaDescription":"Microchip DSC400-0244Q0009KE1T XO (Standard) MEMS oscillator, dual 100 MHz outputs, HCSL/LVPECL, 2.25V–3.6V supply, ±50 ppm stability, -20°C~70°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":"HCSL, LVPECL","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":"100MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/77ffd765db63125e580fcfaaeda2a320.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-0244Q0009KE1T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy DSC400-0244Q0009KE1T and how do I get a price?","answer":"This part is Active and available through independent distribution.
