General Description

The USB5534B hub is a 4-port SuperSpeed/Hi-Speed,

low-power, configurable hub controller family fully com-

pliant with the USB 3.0 Specification. The USB5534B

supports 5 Gbps SuperSpeed (SS), 480 Mbps Hi-

Speed (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 con-

troller 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 non-

USB 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 exter-

nal SPI ROM, or SMBus.
