The enable/disable function lets the system gate the clock output for power saving or test modes; when disabled, the supply current drops to 23 mA typ, which is still relatively high — this is a power-on gating feature, not a deep-sleep trick. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits space-constrained automotive modules like radar sensors or camera ECUs where board real estate is at a premium.","metaTitle":"DSC1221DA3-21M00000T MEMS XO – 21 MHz, AEC-Q100, CMOS Output","metaDescription":"Microchip DSC1221DA3-21M00000T MEMS oscillator: 21 MHz, ±20 ppm, CMOS, AEC-Q100, -40°C to 125°C, 6-VDFN.
