The supply range is 2.25V to 3.6V, so the same order code works on a 2.5V or 3.3V rail without a separate voltage variant. The 6-VDFN package measures 3.20mm x 2.50mm with a seated height of 0.90mm. The 0.50mm pitch lands are on the bottom — the PCB land pattern should match the VDFN-6 recommended footprint in the datasheet. No through-hole or edge-mount option; this is a surface-mount-only part. Microchip lists the DSC1121CL5-080.0000 as Active.","metaTitle":"DSC1121CL5-080.0000 MEMS XO 80 MHz CMOS ±10ppm -40°C~105°C","metaDescription":"Microchip DSC1121CL5-080.0000 MEMS oscillator, 80 MHz, CMOS output, ±10ppm stability, 2.25V-3.6V supply, -40°C to 105°C, 6-VDFN package.","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":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"80 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","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":"DSC1121","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"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/DSC1121CL5-080.0000/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1121CL5-080.0000 a direct replacement for older quartz oscillator models?","answer":"Functionally yes — it outputs a CMOS clock at 80 MHz with the same logic levels as a quartz oscillator. The MEMS resonator is less sensitive to vibration and temperature shock, and it does not require external load capacitors. However, the 6-VDFN package footprint may differ from older quartz oscillators in larger packages (e.g., 7mm x 5mm). Verify the PCB land pattern against the VDFN-6 footprint before committing the BOM."},{"question":"Can DSC1121CL5-080.0000 be used with a 3.3V supply?","answer":"Yes. The supply range is 2.25V to 3.6V, so both 2.5V and 3.3V rails are within spec. The CMOS output swing follows the supply voltage — at 3.3V the output high is approximately 3.3V, compatible with 3.3V logic inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CL5-080.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CL5-080.0000 when reusing this data.
