The 1.8V supply rail matches low-voltage core domains in MCUs and FPGAs, eliminating the need for a separate level translator on the oscillator supply. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1018DI1-050.0000T MEMS Oscillator – 50 MHz, ±50 ppm","metaDescription":"Microchip DSC1018DI1-050.0000T: 50 MHz XO, CMOS output, ±50 ppm stability, 1.8V, -40°C to 85°C, 4 mA typ, 1 µA standby.
