CMOS output swings rail-to-rail, which is directly compatible with most FPGA, MCU, and PHY clock inputs — no level translation or AC-coupling needed. The Enable/Disable function (pin-controlled) lets the system shut off the oscillator to save power — the disable current is 22 mA max versus 35 mA max when running, a 37% reduction that matters in battery-backed or sleep-mode designs. Cut Tape is available for prototyping or low-volume builds.","metaTitle":"DSC1121CI2-125.0000T MEMS XO 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CI2-125.0000T — 125 MHz MEMS oscillator, CMOS output, ±25 ppm stability, -40 to 85°C, AEC-Q100 qualified.
