TUSB544RNQT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power planes. Use a common mode filter and a shielded cable to minimize EMI.
  • Use a high-quality USB 3.2 Gen 2 cable, ensure the PCB is designed for high-speed signals, and follow the recommended layout guidelines. Also, make sure the device is powered from a stable 3.3V supply.
  • The maximum cable length supported is 3 meters, but it's recommended to use cables shorter than 2 meters for optimal performance and to minimize signal degradation.
  • Use a low-dropout regulator (LDO) to regulate the 3.3V supply, and ensure the power supply can provide enough current to support the device's power requirements.
  • The device has a thermal pad that must be connected to a solid ground plane to dissipate heat. Ensure good airflow around the device, and consider using a heat sink if the device is expected to operate in high-temperature environments.
