Listed as Active — Microchip continues production with no announced end-of-life. This is a current design-in part suitable for new BOMs and volume production.","metaTitle":"DSC1121BI5-125.0000 MEMS XO 125 MHz CMOS AEC-Q100 –","metaDescription":"Microchip DSC1121BI5-125.0000 XO (Standard) MEMS oscillator, 125 MHz CMOS output, ±10ppm stability, -40°C to 85°C, AEC-Q100.
