The enable/disable function lets the system gate the clock output; when disabled the supply current drops to 22 mA max from the 35 mA max active draw. ## Active lifecycle — available for new designs This is a current-production part suitable for both new designs and ongoing production. The MEMS construction avoids the quartz supply constraints that occasionally affect crystal-based oscillators.","metaTitle":"DSC1121BI2-066.6666 MEMS XO 66.6666 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121BI2-066.6666 MEMS oscillator, 66.6666 MHz, CMOS output, ±25 ppm stability, -40°C to +85°C, AEC-Q100.
