The 10 MHz to 170 MHz range covers common MCU clock inputs, Ethernet PHY reference clocks, and FPGA core frequencies — a single BOM line can serve multiple frequency variants by programming the blank part at the distributor or in-house. ## Package and board integration Surface-mount assembly with tube packaging; the Enable/Disable pin is active-low by default on the DSC8121 family — verify the logic polarity against the downstream clock buffer or MCU's enable input.","metaTitle":"DSC8121BI2 MEMS XO, 10-170 MHz, CMOS, ±25 ppm, Active","metaDescription":"Microchip DSC8121BI2 MEMS oscillator, XO type, CMOS output, 10-170 MHz, ±25 ppm stability, -40 to 85°C, 6-SMD.
