If a board with this part shows clock jitter, check the decoupling cap first, not the oscillator itself. The DSC1121 series is still in volume production, so you can commit the BOM line without worrying about a sudden obsolescence notice next quarter.","metaTitle":"DSC1121BI2-024.5760T MEMS XO – Microchip, 24.576 MHz, CMOS","metaDescription":"Microchip DSC1121BI2-024.5760T MEMS oscillator, 24.576 MHz CMOS output, ±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)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"24.576 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","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/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121BI2-024.5760T/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1121BI2-024.5760T RoHS compliant?","answer":"The evidence does not list a RoHS status, but Microchip's DSC1121 series is generally RoHS-compliant.
