Maximum supply current is 35 mA when enabled; the disable function drops it to 22 mA max, useful for power-sensitive designs that gate the clock in sleep modes. ## Package and board layout Housed in a 6-VDFN with exposed pad, 7.00 mm x 5.00 mm footprint, 0.90 mm seated height — the exposed pad needs a thermal via pattern under the package for heat sinking and mechanical stability during reflow. Surface-mount only; the 6-pad DFN is hand-solderable with a fine-tip iron and flux, but a hot-air station or reflow oven gives a more consistent fillet on the exposed pad.","metaTitle":"DSC1121AE5-025.0000 MEMS XO 25 MHz ±10 ppm CMOS – Microchip","metaDescription":"DSC1121AE5-025.0000: MEMS-based XO, 25 MHz, CMOS output, ±10 ppm stability, 2.25-3.6 V supply, 6-VDFN package.
