Supplied in Tape & Reel (TR), which is the expected format for automated assembly. Check the MSL before the reflow profile — the VDFN package typically carries MSL 1 or 2, but confirm on the reel label to avoid popcorning.","metaTitle":"DSC1121BI5-025.6000T MEMS Oscillator 25.6 MHz CMOS ±10 ppm","metaDescription":"Microchip DSC1121BI5-025.6000T XO (Standard) 25.6 MHz CMOS output, ±10 ppm stability, 2.25V-3.6V supply, -40°C to 85°C, 6-VDFN.","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":"25.6 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","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":"±10ppm","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/DSC1121BI5-025.6000T/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1121BI5-025.6000T a direct drop-in replacement for standard 25.6 MHz CMOS oscillators?","answer":"Yes, the DSC1121BI5-025.6000T is a standard XO with CMOS output in a common 5.0 mm x 3.2 mm 6-VDFN footprint. It is a drop-in replacement for any 25.6 MHz CMOS oscillator with the same package and pinout — no board spin needed. The MEMS resonator adds better shock tolerance versus quartz, but the electrical interface is identical."},{"question":"What are the benefits of MEMS vs quartz oscillators?","answer":"MEMS oscillators like this one offer better shock and vibration tolerance compared to quartz crystals, and typically have faster startup times. They also eliminate the quartz crystal's aging drift over temperature. The trade-off is that MEMS oscillators are often slightly higher cost at equivalent stability grades."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BI5-025.6000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BI5-025.6000T when reusing this data.
