Supply voltage spans 1.8 V to 3.3 V, so the same oscillator can be shared across a 3.3 V MCU and a 1.8 V FPGA bank without a level translator — one BOM line covers two rails. The 4-SMD no-lead package (2.50 mm × 2.00 mm, 0.90 mm seated height) uses a standard MEMS-oscillator footprint shared across the DSC1001 family. No pin-compatible alternate is listed; the base product number DSC1001 covers multiple frequency and stability variants.","metaTitle":"DSC1001DI2-018.4320T – Microchip MEMS XO, 18.432 MHz, CMOS","metaDescription":"Active-production Microchip DSC1001DI2-018.4320T MEMS oscillator: 18.432 MHz, CMOS output, ±25 ppm stability, 1.8–3.3 V, AEC-Q100.","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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"18.432 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output frequency of DSC1001DI2-018.4320T?","answer":"18.432 MHz, CMOS output.
