MEMS resonator replaces quartz — 50 MHz fixed output
The DSC1522JI3A-50M00000 is a MEMS-based XO (Standard) that delivers a fixed 50 MHz LVCMOS output from a 2.5V to 3.3V supply rail. The MEMS resonator eliminates quartz crystal startup delays and reduces sensitivity to vibration and shock — a practical advantage in industrial and outdoor equipment where a quartz oscillator might fail to start or drift under mechanical stress.
Microchip lists the DSC1522JI3A-50M00000 as Active.
