The output is CMOS, same as a standard quartz oscillator. Package is 4-SMD, No Lead Exposed Pad, 7.00mm x 5.00mm — the same footprint as many 7x5 mm quartz XOs. In most designs it is a drop-in replacement, but check the enable/disable logic polarity and the start-up time in the datasheet; MEMS oscillators often have faster start-up than quartz.","metaTitle":"DSC1001AI2-018.4320T MEMS XO – 18.432 MHz CMOS, AEC-Q100","metaDescription":"Microchip DSC1001AI2-018.4320T MEMS oscillator: 18.432 MHz, CMOS output, ±25 ppm stability, AEC-Q100, -40°C to 85°C.
