Each downstream port supports two-color status indicator, with automatic and manual modes compliant to USB specification Revision 2.0 (Not supported on SSOP 28 package).

This is a performance better choice for USB 2.0 hub. Multiple TT provides individual TT control logics for each downstream port This is the most cost effective solution for TT − Single TT shares the same TT control logics for all downstream port devices − Support downstream port configuration by reading external EEPROM − Support customized PID, VID by reading external EEPROM − Backward compatible to USB specification Revision 1.1 − 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload) − Downstream ports support HS, FS, and low-speed (LS) traffic − Upstream port supports both high-speed (HS) and full-speed (FS) traffic − Support 4/3/2 downstream ports by I/O pin configuration

Compliant to USB specification Revision 2.0.

Traffic speed between the upstream port and the downstream ports. *TT (transaction translator) is the main traffic control engine in an USB 2.0 hub to handle the unbalanced Please refer to GL852 datasheet for more detailed information. Genesys Logic also provides GL852 for multiple TT hub solution to target on systems which require higher performance for full/low-speed devices, like docking station, embedded system … etc. To fully meet the cost/performance requirement, GL850G is a single TT hub solution for the cost requirement. Number of downstream ports setting can be configured by IO setting in absence of EEPROM. Please refer the table in the end of this chapter for more detail.

The GL850G is a full function solution which supports both Individual/Gang power management modes and the two-color (green/amber) status LEDs. GL850G also support both Individual and Gang modes (4 ports as a group) for power management.

to Chapter 5).Įach downstream port of GL850G supports two-color (green/amber) status LEDs to indicate normal/abnormal status. The more complicated settings such as PID, VID, and number of downstream ports settings are easily achieved by programming the external EEPROM (Ref. GL850G is designed for customers with much flexibility. Default settings in the internal mask ROM is responded to the host without having external EEPROM. Firmware of GL850G 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. GL850G embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Also, GL850G’s power enable pin supports both high-enable and low-enable power switch that provides better flexibility on component selection. GL850G integrated both 5V to 3.3V and 3.3V to 1.8V voltage drop regulator into single chip, therefore no external LDO required. GL850G provides multiple advantages to simplify board level design that help achieve lowest BOM (bill of material) for system integrator. GL850G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.
