Product details

163.84 MHz MEMS XO with AEC-Q100 qualification

The Enable/Disable function lets the system shut down the oscillator output without removing supply, cutting supply current to 22 mA max from the 35 mA max active draw.

Supply flexibility and MEMS resonator advantage

A wide 2.25V to 3.6V supply range means the oscillator can run from a 2.5V or 3.3V rail without an external LDO, simplifying power distribution in mixed-voltage designs. The MEMS base resonator eliminates the quartz crystal start-up time and vibration sensitivity typical of traditional oscillators, making it a fit for automotive and industrial environments where mechanical shock is present.
