It replaces a quartz crystal + oscillator circuit in one surface-mount package, with the MEMS resonator immune to the vibration and aging issues that plague quartz in harsh environments. The 4-VDFN package (3.20mm x 2.50mm) is a standard footprint for MEMS oscillators, making it a drop-in for many existing clock sockets. Normal operation draws 8 mA max from a supply rail that can be anywhere from 1.8V to 3.3V, so the same oscillator works across 1.8V, 2.5V, or 3.3V logic domains without a level translator.","metaTitle":"DSC1001CI1-018.4320 MEMS XO – 18.432 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001CI1-018.4320 MEMS XO, 18.432 MHz CMOS output, AEC-Q100, -40 to 85°C, standby mode.
