A single 2.25V–3.6V supply rail powers both outputs, which means one oscillator replaces two quartz cans and the associated bypass caps on a dense board. ## Supply flexibility and enable/disable control The wide 2.25V–3.6V supply range lets this oscillator run from a 2.5V or 3.3V rail without an external LDO — useful when the FPGA bank voltage is not a standard 3.3V. An Enable/Disable function on the package lets the system hold the outputs in high-Z during power sequencing or sleep modes, cutting power draw without a separate clock buffer. ## 20-VFQFN footprint and thermal pad The 5.00 mm x 3.20 mm body with 0.90 mm height fits under a mezzanine card or behind a connector; the exposed pad on the 20-VFQFN package requires a thermal via array under the pad to keep the MEMS die within its temperature spec during high-airflow environments.","metaTitle":"DSC400-0202Q0108KE2 MEMS XO – Dual LVPECL Output, ±25ppm","metaDescription":"Microchip DSC400-0202Q0108KE2 MEMS XO, 167.1875/173.28125 MHz LVPECL, ±25ppm stability, 20-VFQFN, -20°C~70°C.
