LVPECL outputs require a 50-ohm to VCC-2V termination; the 2.25-3.6 V supply range gives flexibility to run off a 2.5 V or 3.3 V rail without a separate regulator. Microchip lists the DSC400-0202Q0109KE2 as Active. ## 20-VFQFN package and board-fit notes Housed in a 20-VFQFN with an exposed pad, measuring 5.00 mm x 3.20 mm and standing 0.90 mm tall. The exposed paddle needs a thermal via array to the ground plane — without it the MEMS die's internal temperature rises above the ambient rating, pulling the frequency stability off the ±25 ppm spec.","metaTitle":"DSC400-0202Q0109KE2 MEMS XO, LVPECL, 153.6/176.875 MHz","metaDescription":"Microchip DSC400-0202Q0109KE2: MEMS-based XO, LVPECL outputs at 153.6 MHz and 176.875 MHz, ±25 ppm stability, 2.25-3.6 V supply, 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":"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":"153.6MHz","Frequency - Output 2":"176.875MHz","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/dafa7ad99233da79a125bb7188cdbad7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-0202Q0109KE2/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0202Q0109KE2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0202Q0109KE2 when reusing this data.
