Frequency stability is ±25 ppm across the temperature range — enough for most PCIe Gen 1/2/3 reference clocks and 1000BASE-T Ethernet without needing a TCXO. ## Active production and MEMS reliability advantage This matters for equipment shipped to sites with mechanical handling or fan vibration.","metaTitle":"DSC2144FE2-E0017 MEMS XO 100MHz 125MHz HCSL Oscillator","metaDescription":"DSC2144FE2-E0017 Microchip Technology MEMS XO, dual 100MHz/125MHz HCSL output, ±25ppm stability, 2.25-3.6V supply, -20 to 70°C, 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","Series":"DSC2144","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":"DSC2144","Frequency Stability":"±25ppm","Frequency - Output 1":"100MHz, 125MHz","Frequency - Output 2":"100MHz, 125MHz","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"60mA (Typ)","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c96f8742bbcba359c467bcb546d0e964.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC2144FE2-E0017/alternatives.json"},"ai":{"faq":[{"question":"What frequencies does DSC2144FE2-E0017 output?","answer":"It outputs two frequencies: 100 MHz and 125 MHz, both on HCSL logic levels.
