Maximum supply current is 27 mA typ when enabled, and 23 mA typ when disabled—the disable current is still high enough that a simple load switch ahead of the oscillator saves more power than relying on the enable pin alone in a sleep-mode design. ## Package footprint and layout consideration The 6-VDFN package measures 5.00mm x 3.20mm with a seated height of 0.90mm max. The 0.197\" x 0.126\" footprint matches the industry-standard 5x3.2 mm oscillator land pattern—no via-in-pad required, but a solid ground pour under the package helps with thermal and EMI. Surface-mount on tape and reel (TR) packaging is standard for automated assembly.","metaTitle":"DSC1221BL2-25M00000T XO Oscillator 25MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1221BL2-25M00000T MEMS XO, 25 MHz, CMOS output, 2.25-3.63V supply, ±25ppm stability, -40°C to 105°C, AEC-Q100.
