The DSC1121CE5-024.5670 is a standard XO (Standard) oscillator built on a MEMS resonator, delivering a 24.567 MHz CMOS output with ±10 ppm frequency stability. That stability figure is tight enough for most serial communication links and microcontroller clock inputs without needing an external temperature-compensation circuit. Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails directly. This wide range lets the same oscillator serve boards with mixed supply domains, eliminating a dedicated LDO for the clock section. It is not qualified for automotive or extended industrial environments.
An Enable/Disable function is built in. Maximum supply current during operation is 35 mA. This is the total current drawn by the MEMS oscillator and output driver at full load — budget this into the power rail sizing for the clock tree.
