Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an extra regulator. ## 6-VDFN package and board layout Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount assembly; the 6-VDFN has a centre pad that should be connected to the ground plane for thermal relief and mechanical stability. Standard reflow profiles for lead-free solder apply.","metaTitle":"DSC1121BI5-022.5792T MEMS XO 22.5792 MHz CMOS - Microchip","metaDescription":"DSC1121BI5-022.5792T XO (Standard) 22.5792 MHz CMOS output, 2.25V-3.6V supply, -40°C to 85°C, ±10 ppm stability.
