It suits outdoor base stations, factory-floor controllers, and under-hood electronics where the ambient can climb well above room temperature. The CMOS output swings rail-to-rail and can drive up to 22 mA max into the load — enough to feed multiple clock inputs on a small PCB without a separate buffer.","metaTitle":"DSC1121BI2-016.3840 16.384 MHz MEMS XO, CMOS, Active","metaDescription":"Microchip DSC1121BI2-016.3840: 16.384 MHz MEMS oscillator, CMOS output, ±25 ppm stability, -40°C to 85°C, 2.25V-3.6V supply.
