The DSC1101DI1-025.0000 is a 25 MHz XO (Standard) oscillator from Microchip's DSC1101 series, built around a MEMS resonator that delivers better shock and vibration tolerance than a quartz crystal — a practical advantage for factory-floor equipment and mobile systems where mechanical stress is routine. CMOS output at 25 MHz feeds directly into the clock input of most MCUs, FPGAs, and Ethernet PHYs without needing an external level translator.
A Standby (Power Down) pin lets the system shut down the oscillator when the clock is not needed — active current is 35 mA max, but the disable current drops to 95 µA max, saving nearly 35 mA in sleep mode.
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — small enough for space-constrained designs like handheld instruments or IoT modules. Surface-mount footprint with a 0.50 mm pitch; the exposed pad on the bottom provides a thermal path to the PCB ground plane, which also helps with decoupling at 25 MHz.
