The AEC-Q100 rating means this part has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up, and extended life — so it is qualified for under-hood and cabin electronics where a standard commercial oscillator would be a single-point failure risk. ## Supply voltage and power budget The supply range spans 1.8V to 3.3V, which covers the common logic rails in automotive ECUs and industrial controllers. Maximum supply current is 7.2 mA — low enough that a standard 100 mA LDO can power this plus several other loads without thermal concern. When the Standby (Power Down) function is asserted, the disable current drops to 15 µA, letting the oscillator sit on a battery-backed rail without draining the cell. ## Package and board layout Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.","metaTitle":"DSC1001CI2-035.4689 MEMS Oscillator – Microchip, 35.4689 MHz","metaDescription":"Microchip DSC1001CI2-035.4689 XO (Standard) MEMS oscillator, 35.4689 MHz CMOS output, ±25 ppm stability, -40°C to 85°C, 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":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"35.4689 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","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)":"7.2mA","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":"Is DSC1001CI2-035.4689 automotive qualified?","answer":"Yes — it carries an AEC-Q100 rating, which qualifies it for automotive-grade applications including under-hood and cabin electronics."},{"question":"Can DSC1001CI2-035.4689 replace a quartz crystal oscillator directly?","answer":"Generally yes, with two caveats. The DSC1001 is a MEMS-based XO (Standard) with a CMOS output — it is a drop-in replacement for a quartz oscillator of the same frequency, output type, and package footprint. However, the MEMS part requires a clean supply rail (the internal PLL is sensitive to ripple), and the Standby (Power Down) function may need a pull-up or pull-down if unused, depending on your circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-035.4689","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-035.4689 when reusing this data.
