It operates from a 1.8V to 3.3V supply rail, drawing a maximum of 7.2 mA active current, and drops to 15 µA in standby (power-down) mode. ## Standby mode and supply flexibility Wide supply range from 1.8V to 3.3V covers common digital core and I/O voltages — no extra level translator needed when the oscillator feeds a 1.8V FPGA bank or a 3.3V microcontroller clock input. ## Automotive and industrial deployment The MEMS resonator construction eliminates quartz crystal aging and start-up reliability concerns common in crystal oscillators.","metaTitle":"DSC1001CI2-066.6666B MEMS Oscillator 66.6666 MHz AEC-Q100","metaDescription":"Microchip DSC1001CI2-066.6666B XO (Standard) CMOS oscillator, 66.6666 MHz, ±25ppm stability, -40°C~85°C, AEC-Q100.
