The 2.25V–3.63V supply range means this one part covers both 2.5V and 3.3V logic rails — no need to stock separate voltage variants for different board designs. For under-hood applications that see 105°C+ ambient, check the DSC1123 family's higher-grade siblings. ## Enable/Disable function and package Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm — the same footprint as standard quartz oscillators, so a board designed for a 3.2x2.5 mm can accepts this MEMS part without a layout change. Listed as Active — Microchip continues to manufacture this order code, and it remains open for new designs.","metaTitle":"DSC1123CI2-250.0000 MEMS XO – 250 MHz LVDS, AEC-Q100, Active","metaDescription":"DSC1123CI2-250.0000: MEMS-based XO, 250 MHz LVDS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
