For a 25 MHz CMOS clock on a 2.25 V to 3.6 V rail, the MEMS structure handles shock and vibration better than a quartz tuning-fork — relevant in an engine-bay or industrial motor-drive environment where quartz crystals can fracture under repetitive 50 g impacts. Listed as Active by Microchip. Sourced to order against the BOM — the 6-SMD no-lead exposed-pad package (7.00 mm × 5.00 mm) is current production, so no last-time-buy scramble. ## Package and footprint constraints 6-SMD, no-lead exposed pad (0.276\" × 0.197\", 0.90 mm seated height). The exposed pad requires a thermal-land pattern on the PCB — not for heat dissipation (35 mA supply max) but for mechanical stability under vibration.","metaTitle":"DSC1121AL2-025.0000T MEMS XO 25 MHz CMOS AEC-Q100 -","metaDescription":"Active DSC1121AL2-025.0000T: AEC-Q100 MEMS oscillator, 25 MHz CMOS output, 2.25-3.6 V supply, -40 to +105°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":"25 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":"±25ppm","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)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy DSC1121AL2-025.0000T and confirm availability?","answer":"No minimum order quantity beyond the reel increment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121AL2-025.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121AL2-025.0000T when reusing this data.
