USB5434

Please consider this device

The Microchip USB5434B hub is a 4-port SuperSpeed/Hi-Speed, low-power, configurable hub controller family fully compliant with the USB 3.0 Specification. The USB5434B supports 5 Gbps SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS) and 1.5 Mbps Low-Speed (LS) USB signalling for complete coverage of all defined USB operating speeds.

The USB5434B supports legacy USB speeds through its USB 2.0 hub controller. The new SuperSpeed hub controller operates in parallel with the USB 2.0 controller, so the 5 Gbps SuperSpeed data transfers are not affected by the slower USB 2.0 traffic.

The USB5434B is configured for operation through internal default settings.
