For procurement, this removes the single-source risk that comes with NRND or obsolete oscillators. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a 0.90 mm seated height, the footprint is compact enough for space-constrained wireless modules or sensor nodes.","metaTitle":"DSC2311KI1-R0051 MEMS XO – Dual 26 MHz CMOS, Industrial Temp","metaDescription":"Microchip DSC2311KI1-R0051 XO (Standard) with MEMS resonator, dual 26 MHz CMOS outputs, ±50 ppm stability, -40°C to 85°C, 2.25V-3.6V supply.
