The MEMS resonator is inherently more shock-tolerant than a quartz crystal — the 4-SMD, no-lead package (3.20mm x 2.50mm) drops onto the same footprint as a standard quartz oscillator, so a board designed for a quartz XO can accept this part without a layout change. ## Supply current and standby power-down","metaTitle":"DSC1033CI2-028.3220T MEMS XO 28.322 MHz CMOS ±25 ppm","metaDescription":"Microchip DSC1033CI2-028.3220T XO (Standard) MEMS oscillator, 28.322 MHz, CMOS output, ±25 ppm stability, 3.3V, -40°C to 85°C, 4-SMD.
