Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator — one less component on the BOM. The oscillator holds ±25 ppm frequency stability across that range, so a telecom basestation or outdoor controller that sees -30°C startup and 70°C steady-state stays within the clock budget. Housed in a 14-VFQFN with exposed pad, 3.20 mm x 2.50 mm footprint, 0.90 mm height. Microchip lists the DSC2042FI2-M0004 as Active.","metaTitle":"DSC2042FI2-M0004 MEMS XO – 125 MHz / 25 MHz HCSL LVPECL","metaDescription":"Microchip DSC2042FI2-M0004 XO (Standard) with MEMS resonator, dual HCSL/LVPECL outputs at 125 MHz and 25 MHz.","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":"DSC2042","Package":"Tube","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"14-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC2042","Frequency Stability":"±25ppm","Frequency - Output 1":"125MHz","Frequency - Output 2":"25MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"76mA (Typ)","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44c3094e23a3acf8019dbf6f002d7405.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC2042FI2-M0004/alternatives.json"},"ai":{"faq":[{"question":"What output logic types does the DSC2042FI2-M0004 support?","answer":"The outputs are configurable as HCSL or LVPECL.
