Each output can be configured as HCSL or LVPECL, which means one device covers both the reference clock for a PCIe switch and the differential clock for an FPGA transceiver bank — no need for two separate oscillators on the same board. For a 100 MHz reference driving a 1 GbE MAC or a PCIe gen2 PLL, that ±25 ppm keeps the accumulated jitter within the receiver's tracking bandwidth — the link does not drop sync on temperature ramps. ## Wide supply and package fit Supply range is 2.25 V to 3.6 V, so the same part runs on a 2.5 V or 3.3 V rail without an intermediate LDO. The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm, 0.90 mm height) needs a thermal via array under the paddle for best heat transfer — the exposed pad is the primary thermal path, not the leads.","metaTitle":"DSC400-0244Q0009KI2 – Microchip MEMS XO, 100 MHz, ±25 ppm","metaDescription":"Microchip DSC400-0244Q0009KI2 XO (Standard), dual 100 MHz HCSL/LVPECL outputs, ±25 ppm stability, 2.25V–3.6V supply, industrial temp, active production.","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":"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":"100MHz","Frequency - Output 2":"100MHz","Frequency - Output 3":"-","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/77ffd765db63125e580fcfaaeda2a320.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency stability and output type for the DSC400-0244Q0009KI2?","answer":"Frequency stability is ±25 ppm.

The MEMS die eliminates the quartz crystal start-up time — the output stabilises faster than a quartz-based oscillator, which matters in hot-plug or fast-recovery applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0244Q0009KI2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0244Q0009KI2 when reusing this data.
