原装现货 GL850G-OHY60 创惟USB2.0集线器控制器

DESCRIPTION

GL850G-60 is Genesys Logic’s advanced STT hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. GL850G-60 inherits Genesys Logic’s cutting edge technology on cost and power efficient serial interface design. GL850G-60 has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.

GL850G-60 provides multiple advantages to simplify board level design that help achieving lowest BOM (Bill of Material) for system integrator. GL850G-60 integrates both 5V to 3.3V and 3.3V to 1.8V low dropout voltage regulator into single chip, therefore no external LDO required.

GL850G-60 embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Firmware of GL850G-60 will control its general purpose I/O (GPIO) to access the external EEPROM and then respond to the host the customized PID and VID configured in the external EEPROM. Default settings in the internal mask ROM is responded to the host without having external EEPROM. GL850G-60 provides better design flexibility for customers. The complicated settings such as PID, VID, and number of downstream ports settings…etc. are easily achieved by programming the external EEPROM or SMBUS mode.

GL850G-60 is a full function solution which supports both Individual and Gang (4 ports as a group) mode for power management (Individual mode is only available in QFN28 package). Number of downstream ports and non/removable downstream port can be configured by different ways, such as EEPROM, SMBUS or I/O strapping. For the detailed configuration methods, please refer to the following table.

*TT (transaction translator) is the main traffic control engine in an USB 2.0 hub to handle the unbalanced traffic speed between the upstream port and the downstream ports.
