For outdoor cabinets or engine-bay use, the wider-temperature DSC1122 variants (e.g., -40°C to 85°C) are the correct choice.","metaTitle":"DSC1122CE5-047.9990T MEMS XO, LVPECL, 47.999 MHz, ±10 ppm","metaDescription":"Microchip DSC1122CE5-047.9990T XO (Standard) MEMS oscillator, 47.999 MHz LVPECL output, ±10 ppm stability, -20°C to 70°C, 6-SMD.
