Worldwide No.1 USB 3.1 Gen 1 Hub Controller with Ensured Compatibility  


GL3520 is a highly-compatible, high performance USB 3.1 Gen 1 hub controller, which integrates Genesys Logic own self-developed USB 3.1 Gen 1 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. GL3520 is a premium 4 port MTT Hub solution, implementing multiple TT* (Note1) architecture that provide dedicated TT* to each downstream (DS) ports, which guarantee Full-Speed(FS) data passing bandwidth when multiple FS device perform heavy loading operations.
GL3520 also complies with USB-IF battery charging specification rev1.2, which can support fast charging function, allowing portable devices to draw up to 1.5A from GL3520 charging downstream ports (CDP) or dedicated charging port (DCP). So it can enable systems to fast charge handheld devices even during “Sleep” and “Power-off” modes.
