The 2.25V to 3.6V supply range covers 2.5V and 3.3V logic rails without a separate regulator, and the Enable/Disable pin lets a system controller gate the output — drawing 22 mA max when disabled versus 35 mA max when active. This matters for power-sensitive ECUs that shut down non-critical clocks during sleep modes.
Yes, the DSC1121CL5-024.7500T carries AEC-Q100 qualification, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up.
Yes, the supply voltage range of 2.25V to 3.6V includes 3.3V. The oscillator can be powered directly from a 3.3V rail without an external LDO, simplifying the power tree.
Yes, it is a drop-in replacement for a 24.75 MHz crystal oscillator module with CMOS output. Because it uses a MEMS resonator rather than a quartz crystal, it does not require external load capacitors and offers better vibration and shock resistance. The Enable/Disable function may require a pull-up or pull-down on the control pin depending on the original circuit.
