CMOS output drives a single-ended clock tree without external termination. The 2.5 V to 3.3 V supply range lets the same BOM position serve both 2.5 V and 3.3 V I/O banks — one line item, two voltage domains. ## MEMS resonator versus quartz 6-VDFN package, 3.20 mm x 2.50 mm body, 0.90 mm seated height — fits the same land pattern as standard 3.2 x 2.5 mm quartz oscillators.","metaTitle":"DSC1221CI3-148M5000T MEMS XO – AEC-Q100, 148.5 MHz, CMOS","metaDescription":"Microchip DSC1221CI3-148M5000T: MEMS-based XO, 148.5 MHz CMOS output, ±20 ppm stability, AEC-Q100 qualified, 2.5-3.3V supply, 6-VDFN package, active lifecycle.","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":"DSC12X1","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"148.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.5V ~ 3.3V","Frequency Stability":"±20ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"27mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"23mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1221CI3-148M5000T/alternatives.json"},"ai":{"faq":[{"question":"How do I check pricing and availability for DSC1221CI3-148M5000T?","answer":"Submit an RFQ with your target quantity.
