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.

FEATURES

● Compliant to USB specification Revision 2.0
