Microchip DSC1101DM2-156.2500T is a MEMS-based XO (Standard) that outputs a fixed 156.25 MHz CMOS clock from a 2.25V to 3.6V supply rail. The MEMS resonator gives it faster startup and better vibration immunity than a quartz-based oscillator — relevant for portable and ruggedized designs where the board sees mechanical stress.
Standby power-down and ±25 ppm stability
Maximum active current is 35 mA at 156.25 MHz; the disable current floor is 95 µA, so a battery-powered sensor logging data once per minute spends most of its life in the low-power state.
Lifecycle status is Active.
