A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the USB connector, and the traces should be kept short and shielded to minimize EMI.
The 1.5kΩ pull-up resistor on the D+ line is required for USB enumeration. It should be connected between the D+ line and the 3.3V power rail. The resistor value can be adjusted based on the specific application requirements.
The TUSB3410IVF supports cable lengths up to 3 meters (10 feet) at full-speed (12 Mbps) and up to 1 meter (3.3 feet) at high-speed (480 Mbps). Longer cable lengths may require repeaters or active cables.
The TUSB3410IVF has an internal overcurrent protection circuit that limits the current to 500mA. Additional external overcurrent protection can be implemented using a fuse or a current-sensing resistor in series with the VBUS line.
The recommended power sequencing is to power up the 3.3V rail first, followed by the VBUS rail. This ensures that the device is properly initialized and configured before the USB bus is powered up.
