Instructions for CY29942AXI

1. Power Supply Connection

   • Connect the VCC pins to a stable 3.3V power supply.
   • Ensure proper decoupling capacitors are placed close to the power pins.

2. Clock Configuration

   • The device requires an external crystal oscillator connected to the XTAL1 and XTAL2 pins for accurate timing.

3. PCI Interface Setup

   • Configure the PCI interface according to the system requirements. Refer to the PCI 2.2 specification for detailed setup instructions.

4. USB Port Connections

   • Connect the downstream USB ports to appropriate connectors ensuring correct orientation and termination resistors as per USB 2.0 specifications.

5. Firmware/Driver Installation

   • Install the necessary drivers for the operating system to recognize and utilize the hub controller effectively.

6. Thermal Considerations

   • Ensure adequate heat dissipation by providing sufficient airflow or using a heatsink if required, especially under high data transfer loads.

7. Testing

   • After installation, verify the operation of each port using standard USB test devices to ensure proper functionality.

8. Storage

   • Store in a dry environment away from static sources when not in use.
