Its 2.25V to 3.6V supply range means the same part can be dropped into a 2.5V or 3.3V clock tree without a separate level translator, simplifying BOM consolidation.","metaTitle":"DSC1121CI2-049.1520T MEMS XO, 49.152 MHz, CMOS, Active","metaDescription":"Microchip DSC1121CI2-049.1520T MEMS oscillator, 49.152 MHz, CMOS output, 2.25-3.6V supply, -40°C to 85°C.
