USB5537B

USB5537B 7-Port SS/HS USB Hub Controller PRODUCT FEATURES General Description The SMSC USB5537B hub is a 7-port SuperSpeed/HiSpeed, low-power, configurable hub controller family fully compliant with the USB 3.0 Specification. The USB5537B 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 USB5537B supports legacy USB speeds through its USB 2.0 hub controller. The new SuperSpeed hub controller (available on 4 of the 7 ports) 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 USB5537B 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 legacy devices. The USB5537B 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.
