Runs from 2.5 V to 3.3 V, covering the common logic rails for automotive microcontrollers and Ethernet PHYs without an extra regulator. Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm—compatible with standard reflow profiles and bottom-side clearance constraints. Sourced through independent distribution per RFQ.","metaTitle":"DSC1221NE3-38M00000T – 38 MHz MEMS XO, AEC-Q100, CMOS Output","metaDescription":"Microchip DSC1221NE3-38M00000T: 38 MHz MEMS XO, ±20 ppm stability, AEC-Q100 qualified, CMOS output, 2.5V-3.3V supply, 6-VDFN 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":"DSC12X1","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"38 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.5V ~ 3.3V","Frequency Stability":"±20ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°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/DSC1221NE3-38M00000T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy DSC1221NE3-38M00000T?","answer":"We source this active Microchip MEMS oscillator to order.
