Housed in a 6-VDFN, 2.50 mm x 2.00 mm footprint with 0.90 mm seated height — the compact land pattern fits tight PCIe Mini Card or M.2 module layouts where a larger 5.0 x 3.2 mm quartz can won't route. Listed as Active by Microchip — no EOL notice, no last-time-buy deadline. The MEMS resonator construction avoids the long lead times and vibration sensitivity of quartz crystals.","metaTitle":"DSC1123DI1-054.0000 - Microchip MEMS XO, 54 MHz, LVDS","metaDescription":"Microchip DSC1123DI1-054.0000: 54 MHz MEMS XO, LVDS output, ±50 ppm stability, -40°C to 85°C, 6-VDFN.
