The 1.8 V–3.3 V supply range means the same part can be dropped onto a 1.8 V core rail, a 2.5 V I/O bank, or a 3.3 V peripheral bus without a separate voltage variant. ## Package and mounting footprint Housed in a 4-SMD, no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The 0.098\" × 0.079\" footprint is common among MEMS oscillators and matches the standard 2.5×2.0 mm XO land pattern — no board respin if swapping from a quartz oscillator of the same size. The DSC1001 series has multiple frequency variants and the same package pinout — a BOM change to a different frequency within the family requires only a new order code, not a board layout change.","metaTitle":"DSC1001DE1-037.1250 – Microchip MEMS XO, 37.125 MHz, CMOS","metaDescription":"Active Microchip DSC1001DE1-037.1250 MEMS oscillator. 37.125 MHz CMOS output, ±50 ppm stability, 1.8–3.3 V supply, 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":"Standby (Power Down)","Frequency":"37.125 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":"-20°C~70°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 the DSC1001DE1 AEC-Q100 qualified for automotive use?","answer":"Yes, the DSC1001DE1 carries AEC-Q100 qualification, meaning it has passed automotive-grade temperature cycling, ESD, and reliability stress tests. The operating temperature range is -20°C to +70°C, which covers cabin and most interior automotive domains but not full under-hood ambient."},{"question":"What is the frequency stability of the DSC1001DE1?","answer":"Rated ±50 ppm over the -20°C to +70°C temperature range. This is typical for a standard MEMS XO and suits most serial-communication reference clocks."},{"question":"Does the DSC1001DE1 include a standby or power-down function?","answer":"Yes, the function is listed as Standby (Power Down). When disabled, the supply current drops to 15 µA maximum, allowing the system to cut the clock output while keeping the oscillator in a low-power state for wake-on-event scenarios."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DE1-037.1250","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DE1-037.1250 when reusing this data.
