This blank stock gives a storeroom keeper flexibility: one SKU covers any frequency in the 10 MHz to 170 MHz range, as long as you have the programming gear. ## Temperature grade and supply tolerance Total frequency stability is ±50 ppm, covering temperature, aging, and supply variation. For a 100 MHz clock, that is ±5 kHz — tight enough for most microcontroller and interface timing budgets. The footprint is standard for MEMS oscillators and compatible with many quartz XO footprints in the same size — a layout swap without board respin is possible if the pinout matches.","metaTitle":"DSC8121CM1 Microchip MEMS XO, CMOS, 10-170 MHz, ±50ppm","metaDescription":"DSC8121CM1 Microchip MEMS XO, CMOS output, 10-170 MHz, ±50ppm stability, -55 to 125°C.
