The Enable/Disable function lets firmware gate the unused outputs during sleep modes. The 5.00 mm x 3.20 mm body with 0.90 mm height fits tight mezzanine card stacks; the exposed pad under the QFN needs a thermal via array to keep the MEMS die within the temperature spec. ## Active status – no LTB window to chase","metaTitle":"DSC400-3331Q0097KE2 MEMS XO – 4 Outputs, 16/50 MHz, ±25 ppm","metaDescription":"Active Microchip DSC400 XO: LVCMOS/LVDS outputs, 16 MHz + 3x 50 MHz, ±25 ppm, -20°C to 70°C. 20-VFQFN.
