It delivers a fixed 27 MHz CMOS output, covering the common frequency for USB, Ethernet, and MCU clock domains. ## Automotive-grade qualification and supply flexibility Its supply voltage range of 1.8V to 3.3V covers the three most common logic rails in automotive and industrial systems, so it can be driven directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate regulator. ## Standby power-down for battery-conscious designs","metaTitle":"DSC1001CI1-027.0000 Microchip MEMS Oscillator, 27 MHz","metaDescription":"Microchip DSC1001CI1-027.0000: XO (Standard) MEMS oscillator, 27 MHz CMOS output, AEC-Q100 qualified, -40°C to 85°C, 1.8V-3.3V supply.
