The HCSL (High-Speed Current Steering Logic) output provides a differential signal with a typical 700 mV swing into a 50-ohm termination, matching the input requirements of most clock buffers and PHYs without external level translation. The 2.25V to 3.6V supply range lets the oscillator operate from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree. No direct replacement or successor is listed; the part is the current offering in the DSC1124 series.","metaTitle":"DSC1124AI1-100.0000 XO (Standard) 100 MHz HCSL MEMS","metaDescription":"Microchip DSC1124AI1-100.0000 XO (Standard) 100 MHz HCSL output, MEMS resonator, -40°C to +85°C, 2.25V-3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"HCSL","Series":"DSC1124","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"100 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1124","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"42mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/11b93dcf3fe2344432ea2f214a7ea724.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1124AI1-100.0000/alternatives.json"},"ai":{"faq":[{"question":"What is the output format of the DSC1124AI1-100.0000?","answer":"The output is HCSL (High-Speed Current Steering Logic), a differential signal format commonly used for PCIe and other high-speed serial interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1124AI1-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1124AI1-100.0000 when reusing this data.
