When the standby (power-down) pin is asserted, the oscillator draws a maximum of 15 µA — low enough that a battery-backed real-time clock domain can keep the oscillator off until a wake event, saving the 7.2 mA active supply current. The 7.2 mA max supply current at 42.5 MHz is typical for a MEMS oscillator at this frequency; the CMOS output swings rail-to-rail, so no external termination resistor is needed for short PCB traces.","metaTitle":"DSC1001BI2-042.5000T MEMS Oscillator – 42.5 MHz, AEC-Q100","metaDescription":"Microchip DSC1001BI2-042.5000T XO (Standard) with CMOS output, 42.5 MHz, AEC-Q100 qualified, -40°C to 85°C, 1.8V-3.3V supply.","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":"42.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1001BI2-042.5000T/alternatives.json"},"ai":{"faq":[{"question":"What is the frequency of the DSC1001BI2-042.5000T?","answer":"42.5 MHz, fixed at the factory.
