4 port USB 2.0 Hub
Low cost 4 port USB 2.0 Hub with both microusb and USB type C connector and External Power Option.
The Hub is deisgned around popular low cost usb 2.0 hub controller GL850G/GL852G from Genesys Logic.
GL850G is Genesys Logic’s advanced version Hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. GL850 inherits Genesys Logic’s cutting edge technology on cost and power efficient serial interface design. GL850G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.
GL850G provides multiple advantages to simplify board level design that help achieve lowest BOM (bill of material) for system integrator. GL850G integrated both 5V to 3.3V and 3.3V to 1.8V voltage drop regulator into single chip, therefore no external LDO required. Also, GL850G’s power enable pin supports both high-enable and low-enable power switch that provides better flexibility on component selection.
GL852G is Genesys Logic’s premium 4-port Hub solution which fully complies with Universal Serial Bus Specification Revision 2.0. GL852G implements 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. The controller inherits Genesys Logic’s cutting edge technology on cost and power efficient serial interface design. GL852G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.
GL852G implements multiple hub configuration features onto internal mask ROM, which traditionally requires one external EEPROM. The microprocessor detects general purpose I/O (GPIO) status during the initial stage to configure hub settings such as (1) number of DSport, (2) declare of compound device (3) gang/individual mode selection…etc. External EEPROM can be removed if no vendor specified PID/VID or product string is required for the application.
