Active supply current is 3mA typ at 20 MHz — the MEMS core draws less than a comparable quartz oscillator at the same frequency, which matters for battery-powered or thermally constrained boards. No direct factory support or warranty applies; buyer assumes date-code and condition risk.","metaTitle":"DSC1033DI1-020.0000 MEMS Oscillator 20MHz CMOS - Microchip","metaDescription":"DSC1033DI1-020.0000 is an obsolete XO (Standard) MEMS oscillator from Microchip, 20 MHz, CMOS output, 3.3V, -40°C~85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"20 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1033DI1-020.0000/alternatives.json"},"ai":{"faq":[{"question":"How can I order the DSC1033DI1-020.0000 or check availability?","answer":"Submit an RFQ through this page.

The DSC1033DI1 is a MEMS-based XO with an integrated resonator and CMOS output; a quartz XO with the same footprint, frequency, and supply voltage may work, but verify the standby (power-down) function and frequency stability (±50ppm) are compatible."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033DI1-020.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033DI1-020.0000 when reusing this data.
