The MEMS resonator replaces the quartz crystal inside the package, so the pinout and footprint match a standard 5.0mm x 3.2mm 4-SMD oscillator — no board spin needed when swapping from a quartz XO. That covers outdoor telecom, motor-drive control boards, and factory-floor PLC modules without needing a separate temperature-compensation circuit. ## Standby power-down and low draw Active current is 3 mA typical at 35.328 MHz. For a battery-powered sensor node that sleeps most of the time, this one pin saves milliamps compared to gating the output externally.","metaTitle":"DSC1033BI1-035.3280T MEMS XO – 35.328 MHz, CMOS, 3.3V","metaDescription":"Microchip DSC1033BI1-035.3280T MEMS oscillator: 35.328 MHz, CMOS output, 3.3V supply, ±50 ppm stability, -40°C to +85°C, standby function.","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":"35.328 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"3.3V","Base Product Number":"DSC1033","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/DSC1033BI1-035.3280T/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1033BI1-035.3280T a drop-in replacement for standard quartz oscillators?","answer":"Yes. The package is a standard 5.0mm x 3.2mm 4-SMD no-lead footprint, and the output is CMOS — same pinout as a quartz XO. The MEMS resonator inside is the difference, not the interface.
