It fits indoor equipment, office networking, and telecom central-office racks, but not outdoor base stations or under-hood electronics where -40°C is required.","metaTitle":"DSC400-2222Q0047KE1T XO (Standard) LVPECL MEMS Oscillator –","metaDescription":"Active-production MEMS XO, LVPECL output, ±50ppm stability, 2.25V-3.6V supply, 20-VFQFN.
