Packaged in a 6-VDFN measuring 2.50mm x 2.00mm with a seated height of 0.90mm — the 0.50 mm pitch land pattern demands careful solder-paste stencil design to avoid bridging. ## Sourcing and lifecycle — active production Product status is Active — the DSC1121 series remains in volume production with no announced last-time-buy or obsolescence notice.","metaTitle":"DSC1121DL2-072.0000 – Microchip MEMS XO, 72 MHz, CMOS","metaDescription":"DSC1121DL2-072.0000 from Microchip Technology: MEMS XO, 72 MHz, CMOS output, ±25 ppm stability, -40 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":"72 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","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)":"-"}},"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/DSC1121DL2-072.0000/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1121DL2-072.0000 a direct replacement for a 72 MHz crystal oscillator?","answer":"No — this is a MEMS-based XO (complete oscillator with integrated resonator), not a bare quartz crystal. A crystal requires an external oscillator circuit; the DSC1121DL2-072.0000 outputs a rail-to-rail CMOS clock and includes an Enable/Disable pin, so it replaces a crystal-plus-oscillator stage, not the crystal alone."},{"question":"What is the closest pin-compatible alternative to the DSC1121DL2-072.0000?","answer":"Within the DSC1121 series, the same 6-VDFN package and pinout is shared across all frequencies. The closest functional sibling is any other DSC1121DL2 variant with the same output format and supply range — the order code suffix encodes frequency, stability, and temperature grade, so a direct drop-in requires matching those three parameters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121DL2-072.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121DL2-072.0000 when reusing this data.
