The 6-SMD no-lead exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) requires a thermal pad on the PCB for heat sinking — the exposed pad is the primary thermal path, so the board layout must include a copper plane under the pad with vias to the inner ground layer.","metaTitle":"DSC1121AM1-024.5760T MEMS XO – 24.576 MHz, AEC-Q100","metaDescription":"Microchip DSC1121AM1-024.5760T XO (Standard) MEMS oscillator, 24.576 MHz CMOS output, ±50 ppm stability, AEC-Q100 qualified, -55°C to 125°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":"AEC-Q100","Function":"Enable/Disable","Frequency":"24.576 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":"DSC1121","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121AM1-024.5760T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121AM1-024.5760T when reusing this data.
