The Enable/Disable function (pin 1 on the 6-SMD package) pulls the output to high-impedance when driven low, reducing supply current from 35mA max to 22mA max — useful for power gating in battery-backed or sleep-mode systems.","metaTitle":"DSC1121BI2-156.2540 MEMS Oscillator – 156.254 MHz, AEC-Q100","metaDescription":"Microchip DSC1121BI2-156.2540 XO (Standard) with CMOS output, 156.254 MHz, ±25ppm stability, 2.25V-3.6V supply, AEC-Q100, active lifecycle.
