PDCore-6 USB HUB
Proje türü
PCB
Tarih
May 2025
This project features a custom-designed, high-speed 6-port USB hub optimized for modern data and video transmission. Built to comply with USB 3.2 Gen 1/2 and DisplayPort Alt Mode, the design also includes full Power Delivery (PD) support and robust power switching. Its compact form and simulation-driven signal integrity strategy make it ideal for embedded and professional hardware systems.
Port Configuration
Port Type Count Standard Direction
USB Type-A 3 USB 3.2 Gen 1 – 5Gbps Downstream
USB Type-C 2 USB 3.2 Gen 2 – 10Gbps 1x Upstream, 1x Downstream
DisplayPort 1 DisplayPort Alt Mode Downstream
Total: 6 physical ports
Upstream port is a USB-C input for host connection.
DisplayPort is output only, handled by a TDP142 redriver.
Engineering Highlights
-TUSB8044A – USB 3.2 Gen 1/2 hub controller
