The 6-SMD no-lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm — a standard MEMS oscillator footprint that drops onto the same land pattern as many quartz XO alternatives.","metaTitle":"DSC1121CI2-050.0000 – Microchip 50 MHz MEMS XO, CMOS","metaDescription":"DSC1121CI2-050.0000: 50 MHz MEMS oscillator, CMOS output, 2.25V–3.6V supply, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
