USB5534B-6080JZXTR

The USB5534B hub is a 4-port SuperSpeed/Hi-Speed, low-power, configurable hub controller family fully compliant with the USB 3.0 Specification. The USB5534B supports 5 Gbps SuperSpeed (SS), 480 Mbps HiSpeed (HS), 12 Mbps Full-Speed (FS) and 1.5 Mbps Low-Speed (LS) USB signaling for complete coverage of all defined USB operating speeds. The USB5534B supports USB 2.0 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 USB5534B supports battery charging on a per port basis. On battery charging enabled ports, the devices provide automatic USB data line handshaking. The handshaking supports USB 1.2 Charging Downstream Port (CDP), Dedicated Charging Port (DCP) and nonUSB 1.2 devices. The USB5534B is configured for operation through internal default settings, where custom configurations are supported through an on-chip OTP ROM, an external SPI ROM, or SMBus.
