This series includes GL852. GL852 embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Firmware of GL852 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 EEROM. GL852 is designed for customers with much flexibility. The more complicated settings such as PID, VID, and number of downstream ports settings are easily achieved by programming the external EEPROM (Ref. to Chapter 5). Each downstream port of GL852 supports two-color (green/amber) status LEDs to indicate normal/abnormal status. To fully meet the performance requirement, GL852 series is a multiple TT hub solution to provide every down stream port with a TT. With the dedicated TT in each down stream port, GL852 can provide the best performance even connect with several Full/Low-Speed devices and running heavy bandwidth-consuming operations concurrently. *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.

Page 15 GL852 USB 2.0 MTT HUB Controller CHAPTER 5 FUNCTION DESCRIPTION 5.1 General 5.1.1 USPORT Transceiver USPORT (upstream port) transceiver is the analog circuit that supports both full-speed and high-speed electrical characteristics defined in chapter 7 of USB specification Revision 2.0. USPORT transceiver will operate in full-speed electrical signaling when GL852 is plugged into a 1.1 host/hub. USPORT transceiver will operate in high-speed electrical signaling when GL852 is plugged into a 2.0 host/hub. 5.1.2 PLL (Phase Lock Loop) GL852 contains a 40x PLL. PLL generates the clock sources for the whole chip. The generated clocks are proven quite accurate that help in generating high speed signal without jitter. 5.1.3 FRTIMER This module implements hub (micro)frame timer. The (micro)frame timer is derived from the hub’s local clock and is synchronized to the host (micro)frame period by the host generated Start of (micro)frame (SOF). FRTIMER keeps tracking the host’s SOF such that GL852 is always safely synchronized to the host. The functionality of FRTIMER is described in section 11.2 of USB Specification Revision 2.0. 5.1.4 µC µC is the micro-processor unit of GL852. It is an 8-bit RISC processor with 2K ROM and 64 bytes RAM. It operates at 6MIPS of 12Mhz clock to decode the USB command issued from host and then prepares the data to respond to the host. In addition, µC can handle GPIO (general purpose I/O) settings and reading content of EEPROM to support high flexibility for customers of different configurations of hub. These configurations include self/bus power mode setting, individual/gang mode setting, downstream port number setting, device removable/non-removable setting, and PID/VID setting. 5.1.5 UTMI (USB 2.0 Transceiver Macrocell Interface) UTMI handles the low level USB protocol and signaling. It’s designed based on the Intel’s UTMI specification 1.01. The major functions of UTMI logic are to handle the data and clock recovery, NRZI encoding/decoding, Bit stuffing /de-stuffing, supporting USB 2.0 test modes, and serial/parallel conversion. 5.1.6 USPORT logic USPORT implements the upstream port logic defined in section 11.6 of USB specification Revision 2.0. It mainly manipulates traffics in the upstream direction. The main functions include the state machines of Receiver and Transmitter, interfaces between UTMI and SIE, and traffic control to/from the REPEATER and TT. 5.1.7 SIE (Serial Interface Engine) SIE handles the USB protocol defined in chapter 8 of USB specification Revision 2.0. It co-works with C to play the role of the hub kernel. The main functions of SIE include the state machine of USB protocol flow, CRC check, PID error check, and timeout check. Unlike USB 1.1, bit stuffing/de-stuffing is implemented in UTMI, not in SIE. 5.1.8 Control/Status register Control/Status register is the interface register between hardware and firmware. This register contains the information necessary to control endpoint0 and endpoint1 pipelines. Through the firmware based architecture, GL852 possesses higher flexibility to control the USB protocol easily and correctly. 5.1.9 REPEATER Repeater logic implements the control logic defined in section 11.4 and section 11.7 of USB specification Revision 2.0. REPEATER controls the traffic flow when upstream port and downstream port are signaling in the same speed. In addition, REPEATER will generate internal resume signal whenever a wakeup event is issued under the situation that hub is globally suspended. ©2000-2007 Genesys Logic Inc. - All rights reserved. Page 16 μ GL852 USB 2.0 MTT HUB Controller 5.1.10. TT (Transaction Translator) TT implements the control logic defined in section 11.14 ~ 11.22 of USB specification Revision 2.0. TT basically handles the unbalanced traffic speed between the USPORT (operating in HS) and DSPORTS (operating in FS/LS) of hub. GL852 adopts multiple TT architecture to provide the most performance effective solution. Multiple TT provides control logics for each downstream port respectively. 5.1.11 REPEATER/TT routing logic REPEATER and TT are the major traffic control machines in the USB 2.0 hub. Under situation that USPORT and DSPORT are signaling in the same speed, REPEATER/TT routing logic switches the traffic channel to the REPEATER. Under situation that USPORT is in the high speed signaling and DSPORT is in the full/low speed signaling, REPEATER/TT routing logic switches the traffic channel to the TT. 5.1.11.1 Connected to 1.1 Host/Hub If an USB 2.0 hub is connected to the downstream port of an USB 1.1 host/hub, it will operate in USB 1.1 mode. For an USB 1.1 hub, both upstream direction traffic and downstream direction traffic are passing through REPEATER. That is, the REPEATER/TT routing logic will route the traffic channel to the REPEATER. USB1.1 HOST/HUB USPORToperating in FS signaling Traffic channel is routed to REPEATER REPEATER TT TT DSPORT operating in FS/LS signaling Figure 5.1 - Operating in USB 1.1 scheme 5.1.11.2 Connected to USB 2.0 Host/Hub If an USB 2.0 hub is connected to an USB 2.0 host/hub, it will operate in USB 2.0 mode. The upstream port signaling is in high speed with bandwidth of 480 Mbps under this environment. The traffic channel will then be routed to the REPEATER when the device connected to the downstream port is signaling also in high speed. On the other hand, the traffic channel will then be routed to TT when the device connected to the downstream port is signaling in full/low speed. ©2000-2007 Genesys Logic Inc. - All rights reserved.

It mainly manipulates the state machine, the connection/disconnection detection, over current detection and power enable control, and the status LED control of the downstream port. Besides, it also output the control signals to the DSPORT transceiver. 5.13 DSPORT Transceiver DSPORT transceiver is the analog circuit that supports high-speed, full-speed, and low-speed electrical characteristics defined in chapter 7 of USB specification Revision 2.0. In addition, each DSPORT transceiver accurately controls its own squelch level to detect the detachment and attachment of devices. 5.2 Configuration and I/O Settings 5.2.1 RESET# Setting GL852 integrates in the pull-up 1.5K resister of the upstream port. When RESET# is enabled, the internal 1.5K pull-up resister will be disconnected to the 3.3V power. To meet the requirement (p.141) of the USB 2.0 specification, pull-up resister should be disconnected while lacking of USB cable power (Vbus). Therefore, we suggest designing the RESET# circuit as following figure to meet the requirement mentioned above. ©2000-2007 Genesys Logic Inc. - All rights reserved. Page 18 GL852 USB 2.0 MTT HUB Controller Figure 5.3 - RESET# (External Reset) setting and application GL852 internally contains a power on reset circuit. The power on sequence is depicted in the next picture. To fully control the reset process of GL852, we suggest the reset time applied in the external reset circuit should longer than that of the internal reset circuit. VCC(3.3V) Power good voltage, 2.5~2.8V Internal reset External reset Figure 5.4 - Power on sequence of GL852 5.2.2 PGANG/SUSPND Setting To save pin count, GL852 uses the same pin to decide individual/gang mode as well as to output the suspend flag. The individual/gang mode is decided within 20us after power on reset. Then, about 50ms later, this pin is changed to output mode. GL852 outputs the suspend flag once it is globally suspended. For individual mode, a pull low resister greater than 100K should be placed. For gang mode, a pull high resister which greater than 100K should be placed. In figure 5.6, we also depict the suspend LED indicator schematics. It should be noticed that the polarity of LED must be followed, otherwise the suspend current will be over spec limitation (2.5mA). ©2000-2007 Genesys Logic Inc. - All rights reserved. μ≒ 2.7 s Page 19 GL852 USB 2.0 MTT HUB Controller RESET# 50 ms GANG_CTL Input mode, strapping to decide individual or gang mode Output mode, indicating GL852 is in normal mode or suspend mode Figure 5.5 - Timing of PGANG/SUSPND strapping GAND Mode DVDD(3.3V) DVDD(3.3V) "0": Individual Mode "1": GANG Mode 100K ohm Suspend LED Indicator SUSPNDO GANG_CTL 100K ohm Inside GL852 On PCB Individual Mode 5.2.3 SELF/BUS Power Setting GL852 can operate under bus power and conform to the power consumption limitation completely (suspend current < 2.5 mA, normal operation current < 100 mA).
