Its CMOS output interfaces directly with MCU, FPGA, and SoC clock inputs without level translation. Frequency stability of ±25 ppm keeps the clock edge within tight timing margins for USB, Ethernet, and serial interfaces over temperature. Housed in a 6-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts without requiring via-in-pad.","metaTitle":"DSC1121BI2-080.0000 MEMS Oscillator – 80 MHz, CMOS, Active","metaDescription":"Microchip DSC1121BI2-080.0000 MEMS XO, 80 MHz CMOS output, ±25 ppm stability, -40°C to 85°C.
