An Enable/Disable function on the package lets firmware gate the outputs during low-power sleep states, pulling the oscillator into a high-impedance state without a downstream clock buffer. ## Board-fit and reflow considerations The 20-VFQFN with exposed pad measures 5.00 mm x 3.20 mm and sits 0.90 mm tall — the exposed pad needs a thermal via array under the package to pull heat into the ground plane; without it the junction temperature rises faster during reflow and the MEMS die sees higher stress.","metaTitle":"DSC400-1111Q0019KI2 MEMS XO – 6-Output, ±25 ppm","metaDescription":"DSC400-1111Q0019KI2: MEMS-based XO, 6 LVCMOS outputs (25/50/125/150/100/156.25 MHz), ±25 ppm stability, -40 to +85°C.
