The 8 MHz fixed frequency with ±25 ppm absolute pull range (APR) holds the clock tight enough for UART baud-rate generation and basic CAN timing without external trimming components. The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails commonly found on Cortex-M and FPGA boards — no separate regulator needed for the oscillator. ## Enable/Disable function and package The 6-VDFN package (5.00mm x 3.20mm x 0.90mm) is a standard 6-pin footprint — the same land pattern used by many 8 MHz quartz oscillators, so a board layout swap is straightforward.","metaTitle":"DSC1121BI2-008.0000 MEMS Oscillator – 8 MHz CMOS XO, Active","metaDescription":"Microchip DSC1121BI2-008.0000: 8 MHz MEMS XO, CMOS output, ±25 ppm stability, -40°C to 85°C, 6-VDFN.
