Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a standard 2.0 x 2.5 mm footprint that matches many MEMS and quartz oscillators. Surface-mount, supplied in tube — the no-lead package has solder pads on the bottom; ensure the PCB land pattern follows the manufacturer's recommended footprint for reliable reflow.","metaTitle":"DSC1001DI1-038.4000 – Microchip MEMS XO, 38.4 MHz, AEC-Q100","metaDescription":"Microchip DSC1001DI1-038.4000 MEMS oscillator: 38.4 MHz CMOS output, 1.8-3.3V supply, ±50 ppm stability, AEC-Q100 qualified.","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":"Enable/Disable","Frequency":"38.4 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":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1001DI1-038.4000/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1001DI1-038.4000 AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications including under-hood and cabin environments."},{"question":"What is the output type of the DSC1001DI1-038.4000?","answer":"CMOS output, single-ended, compatible with most digital logic families."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI1-038.4000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI1-038.4000 when reusing this data.
