A single 20-VFQFN package with exposed pad replaces two discrete oscillators, saving board space and reducing BOM count for dual-clock systems like Ethernet switches or FPGA reference clock trees. Operating from 2.25 V to 3.6 V, this oscillator can be powered directly from a 2.5 V or 3.3 V rail without an intermediate regulator — the wide tolerance covers both nominal rails and their ripple. ## Frequency stability and package fit The 5.00 mm × 3.20 mm × 0.90 mm VFQFN package with exposed pad requires a thermal via array under the pad for proper heat sinking; the 0.50 mm pitch pads need a 4-layer PCB for reliable fan-out.","metaTitle":"DSC400-0202Q0107KI2T Dual LVPECL Oscillator – Microchip","metaDescription":"DSC400-0202Q0107KI2T: MEMS XO, dual LVPECL outputs at 161.1328125 MHz & 164.375 MHz, ±25 ppm stability, 2.25–3.6 V supply, -40 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":"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":"±25ppm","Frequency - Output 1":"161.1328125MHz","Frequency - Output 2":"164.375MHz","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/0cecb08ad574fed3be7cf1fcd38d37aa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact output frequencies of the DSC400-0202Q0107KI2T?","answer":"Output 1 is 161.1328125 MHz and output 2 is 164.375 MHz, both LVPECL."},{"question":"What supply voltage range does the DSC400-0202Q0107KI2T accept?","answer":"It operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an extra regulator."},{"question":"Does the DSC400-0202Q0107KI2T have an enable/disable function?","answer":"Yes, the enable/disable pin lets you shut down the outputs to high-Z for power savings or clock gating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0202Q0107KI2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0202Q0107KI2T when reusing this data.
