Microchip USB5826六端口USB 3．1 Gen 1智能集线器解决方案

Microchip公司的USB5826是六端口USB 3.1 Gen 1智能集线器控制器,支持双USBType-CTM DFP,具有用于嵌入USB应按用的先进特性.USB5826完全和USB Revision 3.1标准和USB 2.0Link电源管理附录兼容.支持5Gbps超速(SS),480 Mbps高速(HS), 12 Mbps全速(FS)和1.5 Mbps低速(LS).USB5826通过专用的USB 2.0集线器控制器还支持以前的确USB速度(HS/FS/LS).超速集线器控制器和USB 2.0集线器控制器并行工作,由于较低的USB 2.0流量解决了5Gbps SS数据传输瓶颈问题.主要用在单独可用的USB集线器,笔记本电脑坞站,PC母板,PC监视器坞站,多功能 USB 3.1 Gen 1外设.中电网为您整理如下详细资料,本文介绍了USB5826亮点,主要特性,应用电路以及评估板EVB-USB5816主要特性,框图,电路图,材料清单和PCB设计图.
6-Port USB 3.1 Gen 1 Smart Hub with Support for Dual USB Type-CTM DFPs
The Microchip USB5826 hub is a low-power, OEM configurable, USB 3.1 Gen 1 hub controller with 6 downstream ports and advanced features for embedded USB applications. The USB5826 is fully compliant with the Universal Serial Bus Revision 3.1 Specification and USB 2.0 Link Power Management Addendum. The USB5826 supports 5 Gbps Super-Speed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream devices on all enabled downstream ports.
The USB5826 supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub controller that is the culmination of five generations of Microchip hub controller design and experience with proven reliability, interoperability, and device compatibility. The SuperSpeed hub controller operates in parallel with the USB 2.0 hub controller, decoupling the 5 Gbps SS data transfers from bottlenecks due to the slower USB 2.0 traffic.
The USB5826 hub feature controller enables OEMs to configure their system using “Configuration Straps.” These straps simplify the configuration process, assigning default values to USB 3.1 Gen 1 ports and GPIOs. OEMs can disable ports, enable battery charging, and define GPIO functions as default assignments on power-up, removing the need for OTP or external SPI ROM....
