The DSC1001CI2-025.0000 is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output in a 4-VDFN package measuring 3.20 mm x 2.50 mm.
The supply voltage spans 1.8V to 3.3V, covering common logic rails without an external regulator—the same BOM line works across a 1.8V MCU or a 3.3V FPGA bank.
The MEMS resonator construction gives inherent shock and vibration tolerance over quartz, a practical advantage for automotive and industrial applications where board-level reliability is a concern.
