Supply voltage accepts 1.8V to 3.3V, covering 1.8V logic, 2.5V I/O, and 3.3V system rails without a separate LDO for the oscillator. ## MEMS resonator vs quartz — the reliability trade That 15 µA standby current is low enough to leave on a always-on battery line in a key-off automotive module without draining the reserve. Product status is Active per Microchip's lifecycle designation. Package is 4-SMD, No Lead, 2.50 mm x 2.00 mm footprint, 0.90 mm seated height. This is a common MEMS oscillator footprint — no unusual layout constraints.","metaTitle":"DSC1001DI5-048.0000 Active AEC-Q100 MEMS Oscillator 48 MHz","metaDescription":"Microchip DSC1001DI5-048.0000 XO Standard 48 MHz, CMOS output, AEC-Q100 qualified, -40°C to 85°C, 1.8V-3.3V supply, 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":"Enable/Disable","Frequency":"48 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":"±10ppm","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":"$1.7400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001DI5-048.0000 qualified for automotive applications?","answer":"Yes — it carries AEC-Q100 rating. This is the formal automotive IC qualification, not a self-declared 'automotive grade'. The qualification covers temperature cycling, ESD, latch-up, and PPAP documentation. Confirm your target temperature grade: -40°C to 85°C (Grade 2) is covered; Grade 0 (150°C) is not."},{"question":"How does DSC1001DI5-048.0000 compare to a standard quartz crystal oscillator?","answer":"The base resonator is MEMS rather than quartz. MEMS oscillators are inherently more resistant to shock and vibration — no crystal blank to fracture. Frequency stability is ±10 ppm, which is tighter than many basic quartz oscillators. Supply range is 1.8V to 3.3V, covering multiple logic families without a regulator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI5-048.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI5-048.0000 when reusing this data.
