Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines for the USB signals.
To ensure signal integrity, use a 50-ohm transmission line for the USB signals, and keep the signal traces as short as possible. Also, use a common mode filter or a ferrite bead to reduce electromagnetic interference (EMI).
The TUSB2046BIVFRG4 supports USB 2.0, which has a maximum cable length of 3 meters (10 feet). However, the actual cable length may vary depending on the specific application and the quality of the cable.
The TUSB2046BIVFRG4 is a USB 2.0 repeater, and it's not compatible with USB 3.0 or USB 3.2 devices. If you need to support higher speeds, consider using a USB 3.0 or USB 3.2 repeater, such as the TUSB9261.
The TUSB2046BIVFRG4 can be powered from the USB bus or from an external power supply. If powered from the USB bus, ensure that the upstream device can provide enough power. If using an external power supply, ensure it's within the recommended voltage range of 3.3V to 5V.
