Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a common footprint shared with many quartz and MEMS oscillators, so a board layout designed for a standard 5×3.2 mm clock can mount this part without a spin.","metaTitle":"DSC1121BI2-022.5792T MEMS Oscillator – 22.5792 MHz, CMOS","metaDescription":"Microchip DSC1121BI2-022.5792T XO (Standard) MEMS oscillator, 22.5792 MHz, CMOS output, ±25 ppm stability, -40°C to +85°C.
