Supply voltage spans 1.8V to 3.3V, allowing the same BOM line to serve 1.8V and 3.3V logic domains without a separate regulator for the oscillator rail. ## Why the Standby (Power Down) function matters The Standby (Power Down) function drops the supply current to 15 µA max when disabled — a useful power-save mode for modules that sleep between CAN bus wake-ups or ignition-off periods. Active current is 7.2 mA max at 49.0909 MHz, so the oscillator itself is not the dominant power draw in most automotive ECUs. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001DI2-049.0909T MEMS Oscillator 49.0909 MHz AEC-Q100","metaDescription":"Microchip DSC1001DI2-049.0909T XO (Standard) 49.0909 MHz CMOS output, ±25 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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"49.0909 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":"±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":"$1.2150","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the DSC1001DI2-049.0909T?","answer":"The DSC1001 series shares the same 4-SMD no-lead footprint and pinout across frequencies.
