Output is CMOS, so it drives logic inputs directly — no external level translation needed for 1.8V, 2.5V, or 3.3V rails within the 1.8V–3.3V supply range. New designs can commit to this part without an early last-time-buy window. Sourced through independent distribution; quoted to order against the BOM line. Availability confirmed at RFQ — no stock-holding claim from this desk. ## Standby power-down — 15 µA disable current The Standby (Power Down) function pulls the output to high-impedance and drops supply current to 15 µA max — useful for battery-backed modules that need to shut the clock tree when the system sleeps. Active supply current is 7.2 mA max at 40 MHz — a fraction of what a canned quartz oscillator with a discrete buffer would consume.","metaTitle":"DSC1001AI1-040.0000T AEC-Q100 MEMS Oscillator 40 MHz CMOS XO","metaDescription":"DSC1001AI1-040.0000T from Microchip Technology: Active XO (Standard) with MEMS resonator, 40 MHz, ±50 ppm, CMOS output, AEC-Q100, -40°C to 85°C.","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":"40 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC1001AI1-040.0000T directly replace a standard 40 MHz quartz oscillator?","answer":"It can replace a standard 40 MHz quartz XO in the same 4-SMD footprint (7.0 x 5.0 mm) and with the same CMOS output.
