Housed in a 3.20mm x 2.50mm 4-SMD no-lead package, 0.90mm seated height, compatible with standard reflow profiles for automated assembly. Maximum supply draw is 10 mA during operation, so the thermal load on the PCB is minimal even in dense layouts.","metaTitle":"DSC1033CI2-028.3220 MEMS XO 28.322 MHz CMOS 3.3V Active -","metaDescription":"DSC1033CI2-028.3220 Microchip MEMS oscillator, 28.322 MHz CMOS output, 3.3V supply, ±25ppm stability, -40°C to 85°C, 4-SMD 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":"DSC1033, PureSilicon™","Ratings":"-","Function":"Standby (Power Down)","Frequency":"28.322 MHz","Packaging":"Tube","Part Status":"Active","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","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)":"10mA","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/DSC1033CI2-028.3220/alternatives.json"},"ai":{"faq":[{"question":"Can DSC1033CI2-028.3220 replace a quartz oscillator in an existing design?","answer":"Yes — the MEMS resonator is pin-compatible with standard 4-pin quartz oscillators in the same 3.2x2.5mm footprint.
