TUSB544RNQR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TUSB544RNQR datasheet, but it's also important to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm impedance-controlled traces for the USB signals.
  • To ensure signal integrity, use a signal integrity analysis tool to simulate the signal transmission and reception. Also, follow the recommended PCB layout, use high-quality components, and ensure that the USB signals are properly terminated and matched to the 50-ohm impedance of the cable.
  • The TUSB544RNQR supports USB 2.0, which has a maximum cable length of 3 meters (10 feet). However, the actual cable length may be limited by the signal attenuation and noise susceptibility of the cable and the system.
  • The TUSB544RNQR is a USB 2.0 repeater, and it's not compatible with USB 3.0 or USB 3.2 systems. If you need to extend the distance of a USB 3.0 or USB 3.2 signal, you'll need a repeater or redriver specifically designed for those speeds.
  • The TUSB544RNQR 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 to the repeater. If powered from an external supply, ensure that it's within the recommended voltage range of 3.3V to 5.5V.
