Max supply current is 35 mA during operation; disabling the output drops consumption to 22 mA max, which matters for battery-backed RTC or sleep-mode power budgets. ## MEMS resonator — why it matters for the BOM The MEMS base resonator eliminates quartz crystal start-up time and shock sensitivity — the oscillator is ready within microseconds of power-on and survives 50,000 g shock. No external load capacitors or feedback resistor: the MEMS oscillator integrates the resonator and the sustaining circuit in one package, saving two passives per clock line.","metaTitle":"DSC1121CL2-050.0000 50 MHz MEMS XO – Microchip, AEC-Q100","metaDescription":"DSC1121CL2-050.0000: 50 MHz MEMS XO, CMOS output, AEC-Q100, -40°C to 105°C, 2.25-3.6V supply.
