The available frequency range spans 10 MHz to 100 MHz, covering most MCU, FPGA, and serial-interface clock requirements. The CMOS output swings rail-to-rail, compatible with most digital inputs without level translation. Tape & Reel packaging supports automated assembly.","metaTitle":"Microchip DSC8121AI5T MEMS XO, CMOS, 10-100 MHz, ±10 ppm","metaDescription":"DSC8121AI5T MEMS-based XO (Standard), CMOS output, 2.25-3.6 V supply, ±10 ppm stability, -40 to 85°C.
