This lets a single order code cover any frequency in the range — you stock one part and program it per design, rather than managing dozens of fixed-frequency SKUs. The ±10 ppm total frequency stability (including initial tolerance, temperature drift, and aging) is tight enough for most serial communication links — UART, I2C, SPI — without external trimming. It is not qualified for automotive under-hood (AEC-Q100) or extended industrial beyond 85°C, so if your design sees 105°C ambient, look at the DSC8121's extended-temperature siblings. The Enable/Disable pin lets you tri-state the output for power sequencing or clock gating without cycling the supply — useful in multi-rail systems where the oscillator must stay running while the load clock is disabled. The base product number is DSC8121, and the series includes multiple stability and temperature options.","metaTitle":"Microchip DSC8121DI5 XO, CMOS, 10-170 MHz, MEMS, Active","metaDescription":"DSC8121DI5 MEMS-based XO, CMOS output, 10 MHz to 170 MHz, ±10 ppm stability, 2.25-3.6 V supply, -40°C to 85°C, 6-SMD.
