Critical Interfaces Impact Placement

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