描述 Description

Genesys GL3590T is a low-power and configurable USB 3.2 Gen 2 hub controller with industrial temperature range (-40° to +85°C) supported. It is compliant with the USB 3.2 specification. GL3590T integrates Genesys Logic self-developed USB 3.2 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. GL3590T 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. GL3590T 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 GL3590T charging downstream ports (CDP1) or dedicated charging port (DCP2). It can enable systems to fast charge handheld devices even during “Sleep” and “Power-off” modes. Available packages of GL3590T are listed in the following table.Product SeriesPackage TypeTotal Ports(UFP+DFP)Power Mgmt.GPIOsGL3590TBGA1443 USB-C SS+3 USB-A SS+Individual/ GangGreen/AmberBGA2894 USB-C SS+2 USB-A SS+3 USB-A HSIndividual/ GangGreen/Amber *Note: TT (transaction translator) implements the control logic defined in Section 11.14 ~ 11.22 of USB specification revision 2.0. TT basically handles the unbalanced traffic speed between the USPORT (operating in HS) and DSPORTS (operating in FS/LS) of hub. 1CDP, charging downstream port, the Battery Charging Rev.1.2-compliant USB port that does data communication and charges device up to 1.5A.2 DCP, dedicated charging port, the Battery Charging Rev.1.2-compliant USB port that only charges devices up to 1.5A, similar to wall chargers.
