The CMOS output swings rail-to-rail across the full 1.8V to 3.3V supply range, so a single order code covers 1.8V, 2.5V, and 3.3V logic rails without a separate voltage variant. Supply voltage range is 1.8V to 3.3V — the oscillator operates across that entire window without adjustment, which simplifies BOM consolidation when the same design uses multiple core voltages. The standby (power-down) function disables the output and drops current consumption to 15µA max, compared to 7.2mA max when active — useful for battery-powered modules that need to wake the clock only during transmission. ## Package footprint and board layout The 4-SMD, No Lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits under a metal shield or on a dense automotive ECU board. ## Temperature grade and reliability","metaTitle":"DSC1001DI1-050.0000B MEMS Oscillator 50MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1001DI1-050.0000B XO (Standard) MEMS oscillator, 50MHz CMOS output, ±50ppm stability, 1.8V-3.3V supply, -40°C~85°C, AEC-Q100.
