The ±25 ppm frequency stability covers most video clock and serial data applications without external tuning. ## Standby power-down and low active current This makes the part suitable for battery-operated equipment that spends most of its life asleep but needs a precise clock on wake. ## Industrial temperature range and 4-SMD package The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that reflows with standard lead-free profiles.","metaTitle":"DSC1033CI2-074.2500T MEMS Oscillator – 74.25 MHz, CMOS, 3.3V","metaDescription":"Microchip DSC1033CI2-074.2500T XO (Standard) MEMS oscillator, 74.25 MHz CMOS output, 3.3V supply, ±25 ppm stability, -40°C to 85°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":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"74.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"4mA (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/DSC1033CI2-074.2500T/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1033CI2-074.2500T compatible with 3.3V systems?","answer":"Yes, the supply voltage is specified as 3.3V, and the CMOS output swings rail-to-rail, so it interfaces directly with 3.3V logic without level translation."},{"question":"What is the footprint of DSC1033CI2-074.2500T?","answer":"The package is a 4-SMD no-lead, 3.20 mm x 2.50 mm body with a 0.90 mm seated height.
