The CMOS output directly drives logic-level clock inputs on MCUs, FPGAs, or Ethernet PHYs without external level translation. Typical supply current is 4 mA max, dropping to 1 µA in standby (power-down) mode via the enable pin. ## Package and board layout notes Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad on the underside provides a thermal path to the PCB ground plane — a solid via pattern under the pad improves heat spreading and mechanical stability during reflow.","metaTitle":"DSC1033AI1-075.0000T MEMS Oscillator 75 MHz CMOS Obsolete","metaDescription":"Microchip DSC1033AI1-075.0000T XO, 75 MHz, CMOS output, MEMS resonator, -40°C to 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":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"75 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a replacement for DSC1033AI1-075.0000T?","answer":"No official successor or pin-compatible replacement is listed by Microchip Technology for this specific order code.
