Its MEMS base resonator replaces a quartz crystal with a silicon die, giving it shock and vibration tolerance suited for industrial environments across -40°C to 85°C. The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, fitting standard oscillator footprints for 100 MHz clock generation. Typical supply current is 5 mA, dropping to 1 µA in standby (power-down) mode — the standby function lets the oscillator be gated off by a logic signal to save power in battery-backed designs.","metaTitle":"DSC1033CI1-100.0000T MEMS Oscillator – Obsolete","metaDescription":"DSC1033CI1-100.0000T is obsolete. 100 MHz CMOS XO, MEMS base, 3.3V, -40°C~85°C, 5 mA typ.","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":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"100 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"5mA (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/DSC1033CI1-100.0000T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1033CI1-100.0000T compatible with standard 100 MHz CMOS logic?","answer":"Yes — the CMOS output at 3.3V supply directly drives standard 3.3V CMOS logic inputs at 100 MHz without a level translator."},{"question":"What replaces the DSC1033CI1-100.0000T?","answer":"Microchip has not published an official successor for this obsolete order code.
