The DSC1033CI2-028.3220T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a fixed 28.322 MHz CMOS output at 3.3V supply. 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.
