Implementation for USB 2.0/USB 3.1 Gen 1 Hub Devices
This application note discusses the PCB layout considerations of Microchip's families of Hub Controller devices such as USB57×4, USB553x, USB25xx, and USB46xx. It is widely applicable to any of Microchip's USB 2.0 and USB 3.1 Gen 1 device implementations.
This application note is written for reader that are familiar with PCB design, including signal integrity, differential signaling, and thermal management implementation concepts.
The goal of this document is to provide implementation information that specifically applies to designing PCBs using Microchip's USB57×4, USB553x, USB25xx, and USB46xx families of Hub Controller devices. Careful implementation of these guidelines enables successful designs.
