It fits the standard 4-SMD, no-lead footprint (3.20mm x 2.50mm) that quartz oscillators use, so it drops onto the same PCB pads without a layout change. ## AEC-Q100 qualification and low-power standby ## Power budget and output drive Maximum active supply current is 6.3 mA at 12.5 MHz — the CMOS output swings rail-to-rail into a standard 15 pF load, so it directly drives the clock input of an MCU or FPGA without a buffer. The 1.8V–3.3V supply range lets it run from the same rail as a 1.8V core or a 3.3V I/O bank without an extra regulator.","metaTitle":"DSC1001CI1-012.5000 MEMS Oscillator 12.5 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1001CI1-012.5000 XO (Standard) MEMS oscillator, 12.5 MHz CMOS output, ±50 ppm stability, -40°C to 85°C, AEC-Q100.
