Genesys Logic

USB3.0 Hub Controller

Genesys GL3521 is a 4-port, low-power, and configurable hub controller. It is compliant with the USB3.0 specification. GL3521 integrates Genesys Logic self-developed USB 3.0 Super Speed transmitter/receiver physical layer (PHY) and USB 2.0 High-Speed PHY. It supports Super Speed, Hi-Speed, and Full-Speed USB connections and is fully backward compatible to all USB 2.0 and USB 1.1 hosts. GL3521 also implements multiple TT* (Note1) architecture providing dedicated TT* to each downstream (DS) port, which guarantees Full-Speed(FS) data passing bandwidth when multiple FS devices perform heavy loading operations. Furthermore, GL3521 has built-in 5V to 3.3V and 5V to 1.2V regulators, which saves customers’ BOM cost, and eases for PCB design.
