The MEMS resonator base gives better shock and vibration immunity than quartz, which matters for engine-mounted or transmission-attached PCBs. ## Enable/Disable function and supply current The Enable/Disable function lets the system gate the oscillator output without cycling the power rail — useful for power-save modes in battery-backed modules. Maximum supply current is 35 mA when enabled; when disabled the current drops to 22 mA max, still drawing from the rail but stopping the output clock.","metaTitle":"DSC1121CI2-030.0000T MEMS Oscillator 30MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CI2-030.0000T XO (Standard) 30MHz CMOS MEMS oscillator, AEC-Q100 qualified, -40°C to 85°C, 2.25V-3.6V supply.
