描述 Description

Genesys GL3590 is a low-power, and configurable USB 3.1 Gen 2 hub controller. It is compliant with the USB 3.1 specification. GL3590 integrates Genesys Logic self-developed USB 3.1 Gen 2 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. GL3590 also implements multiple TT 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. GL3590 features the native fast-charging and complies with USB-IF battery charging specification rev1.2. With different configurations, it could fast-charge Apple devices with up to 2.4A, Samsung Galaxy devices, and any device complaint with BC1.2/1.1. It also allows portable devices to draw up to 1.5A from GL3590 charging downstream ports (CDP) or dedicated charging port (DCP). It can enable systems to fast charge handheld devices even during “Sleep” and “Power-off” modes.
