Its supply voltage spans 1.8V to 3.3V, meaning the same oscillator can be dropped into a 1.8V-core SoC or a 3.3V peripheral bus without a separate level translator — the CMOS output swings rail-to-rail at the supply voltage present. ## AEC-Q100 Grade 1 and industrial temperature range The 4-SMD no-lead exposed-pad package (7.00 mm × 5.00 mm, 0.90 mm seated height) provides a low-profile footprint suitable for dense PCB layouts; the exposed pad improves thermal conduction to the board, though the 6.5 mA max supply current generates minimal self-heating.","metaTitle":"DSC1001AI5-012.2880 MEMS XO 12.288 MHz CMOS AEC-Q100 –","metaDescription":"Microchip DSC1001AI5-012.2880 MEMS XO, 12.288 MHz CMOS output, 1.8V–3.3V supply, ±10 ppm stability, AEC-Q100 qualified, 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":"DSC1001","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"12.288 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"6.5mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output frequency and supply voltage of the DSC1001AI5-012.2880?","answer":"The output frequency is 12.288 MHz with a CMOS output.
