TUSB8020BPHP datasheet by Texas Instruments

TUSB8020BPHP Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TUSB8020BPHP?
  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 differential pairs should be routed close together and away from noise sources.
• How do I ensure signal integrity and minimize electromagnetic interference (EMI) with the TUSB8020BPHP?
  Use a common-mode filter, such as a ferrite bead, on the USB differential pairs. Also, ensure that the PCB layout follows good signal integrity practices, such as minimizing trace lengths and using shielding where possible.
• What is the maximum cable length supported by the TUSB8020BPHP?
  The TUSB8020BPHP supports cable lengths up to 3 meters, but this can vary depending on the specific application and cable quality. It's recommended to use high-quality, shielded cables to minimize signal degradation.
• How do I configure the TUSB8020BPHP for low-power operation?
  The TUSB8020BPHP has a built-in low-power mode that can be enabled by setting the EN pin low. Additionally, the device can be put into a low-power state by disabling the transmitter and receiver circuits when not in use.
• What are the thermal considerations for the TUSB8020BPHP?
  The TUSB8020BPHP has a maximum junction temperature of 150°C. Ensure good airflow around the device, and consider using a heat sink if the device is expected to operate in high-temperature environments.
