Figure 1-1: ISP1521 Hub Demo Board
2. ISP1521 Hub Demo Board Features
• Complies with Universal Serial Bus Specification Rev. 2.0
• Supports self-powered operation
• Configurable number of downstream facing ports (from two to seven)
• Customizable Vendor ID, Product ID and Serial Number (by using an external EEPROM or

3. System Requirements
This hub can be attached to a computer that has a USB or Hi-Speed USB host installed, and
running any of these operating systems:
• Windows®98
• Windows Me
• Windows 2000
• Windows XP
• MacOS®.
If the hub is plugged into a USB host controller, it will work only as a full-speed hub.
4. Power SupplyAdapter Requirements
Regulated Output: 5.1 VCC ± 5%, 4 A.
Warning: The power plug polarity is (-) at the core and (+) at the outer shield.
5. Hub Demo Board Description
5.1. ISP1521 80-Pin LQFP Package
The ISP1521 has these port configurations:
• One Hi-Speed USB and USB capable upstream facing port (USB0), and
• Seven Hi-Speed USB and USB capable downstream facing ports (USB1, USB2, USB3, USB4,
USB5, USB6, USB7).
The port numbers are marked near the USB connectors on the silkscreen. The downstream
facing ports USB3, USB4, USB5, USB6 and USB7 can be disabled. Disabling a port will also disable
all higher-number ports. For example, disabling port USB4 will disable ports USB5, USB6 and
USB7 as well. Therefore, apart from port USB7, it is not possible to selectively disable a port
(For example, only USB5.). By design, ports USB1 and USB2 cannot be disabled.
Table 5-1: Jumper Settings vs. Port Activation
*—Default settings.
These jumpers are set to “ON” by placing a solder joint on the provided footprints.

5.2. Port Indicators
The D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13 and D14 are port indicators.
Conforming to the Universal Serial Bus Specification Rev. 2.0, each downstream facing port has two
port indicators—green and amber—placed to its right.
If the green LED is ON, it means the device connected to the port was successfully enumerated
and is functional.
If the amber LED is ON, it means there is an overcurrent condition.
Custom software applications or drivers may flash these LEDs to attract user attention.
5.3. Power LED Indicator
When power is supplied to the board, LED D16 lights up (red).
5.4. GoodLink Indicator
A Philips GoodLinkTM LED D15 (red) is located near the upstream facing port. This LED blinks on
every successful USB transactions.

5.5. Port Power Switch Transistors
The hub switches on or off the bus power to each downstream facing port through a low ohmic
PMOS transistor.
5.6. Overcurrent Circuit Detection
The integrated analog overcurrent detection circuit of the ISP1521 senses the voltage drop
across the power switch. When the port draws too much current, the voltage drop across the
power switch exceeds the trip voltage threshold. The overcurrent circuit detects this and
automatically switches off the power switch. More information on choosing the switch and
trimming the overcurrent detection voltage can be found in the ISP1521 Hi-Speed Universal Serial
Bus hub controller data sheet.
5.7. Power Supply
To power up the hub, plug the power supply into the power supply socket (PWR_C1).
Jumper J15 will set the powering mode in the hub’s descriptors as self-powered hub; see
Table 5-2.

5.8. I2C-Bus Interface
The ISP1521 can use either its USB descriptors from the internal ROM, or from an external I2C-
BusTM EEPROM or microcontroller. Mode selection is done through jumpers J11and J12 (see
Table 5-3).
Table 5-3: Mode Selection Using J11 and J12
*—Default settings.
An external I2C-Bus controller acting as a master can also be used to update hub descriptors
through the CN1 connector.
Note: The I2C-Bus external EEPROM cannot be programmed on-board.

5.9. Other Jumpers
5.9.1. J13 (NOOC)
This jumper will set the OC capabilities in the hub’s descriptors (see Table 5-4).
Table 5-4: Overcurrent Support Selection Using J11 and J12
*—Default settings.
Note: this jumper is for setting the hub’s descriptor only. To inhibit the overcurrent detection,
the OC pins must be tied to VCC (5 V)
5.9.2. J14 (SUSPEND)
This jumper is provided for debugging purposes. Logic 1 on the SUSPEND signal indicates that
the hub is in the suspend mode. In the default setting jumper J14 is used (pulled down to GND).

7. Installing the Board
Assuming that you have already installed the USB host adapter (including drivers) on a computer
running Windows, installing the hub is fairly simple.
1. Plug in power from the power supply to the hub. The power supply must meet the
requirements specified in Section 4.
2. Plug a USB cable in the USB0 port, and connect the other end of the cable to the USB host.
After a while the GoodLink LED (D15) will start to blink. This means that the enumeration
process has successfully completed and the hub is now ready for use.
You can check the driver installation in the Device Manager window. To check whether the
hub is correctly installed in high-speed, choose the View-Devices by connection command
in the Device Manager window.
3. Plug in devices to the downstream facing ports. After these devices are properly
enumerated, the green LEDs will turn ON.
