7 Critical Interfaces Impact Placement

Placement of the AM62 device and some of the component and / or connectors will also be dictated by some of the highest performance interfaces such as DDR, USB etc. Additionally, due to the PCB losses at multi-gigabit rates, there are routing distance limits that may also limit component placement.
