GENERAL DESCRIPTION
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
- 4 downstream ports
- Upstream port supports both high-speed (HS) and full-speed (FS) traffic
- Downstream ports support HS, FS, and low-speed (LS) traffic
- 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe
(endpoint 1, 1-byte data payload)
- Backward compatible to USB specification Revision 1.1
● On-chip 8-bit micro-processor
- RISC-like architecture
- USB optimized instruction set
- Dual cycle instruction execution
- Performance: 6 MIPS @ 12MHz
- With 64-byte RAM and 2K internal ROM
- Support customized PID, VID by reading external EEPROM
- Support downstream port configuration by reading external EEPROM
● Multiple Transaction translator (MTT)
- MTT provides respective TT control logics for each downstream port.
● Each downstream port supports two-color status indicator,
with automatic and manual modes compliant to
USB specification Revision 2.0
● Built-in upstream port 1.5KΩ pull-up and downstream port 15KΩ pull-down resistors
● Support both individual and gang modes of power management
and over-current detection for downstream ports
● Conform to bus power requirements of USB 2.0 specification
● Automatic switching between self-powered and bus-powered modes
● Integrate USB 2.0 transceiver
● Embedded PLL support external 12 MHz crystal / Oscillator clock input
● Optional 27/48 MHz Oscillator clock input
(Only available in LQFP48/ LQFN46 package)
