The available frequency range is 10 MHz to 100 MHz, covering common reference clocks for MCUs, FPGAs, and Ethernet PHYs. ## Supply voltage and output — single-rail flexibility The CMOS output swings rail-to-rail, which is compatible with most digital logic inputs. That is tight enough for UART bit-rate accuracy, CAN bus, and most serial interfaces without needing a temperature-compensated oscillator.","metaTitle":"DSC8121CI5T MEMS XO, CMOS, ±10 ppm, -40 to 85°C","metaDescription":"Microchip DSC8121CI5T MEMS XO, CMOS output, ±10 ppm stability, 10-100 MHz, 2.25-3.6V, industrial temp, active production.
