TUSB551RWBR datasheet by Texas Instruments

TUSB551RWBR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TUSB551RWBR?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'TUSB551RWBR PCB Layout Guidelines' application note (SLUA623).
• How do I ensure signal integrity on the USB lines?
  To ensure signal integrity, use a differential pair for the USB data lines (D+ and D-), keep the traces as short as possible, and use a common mode filter or a USB signal repeater if necessary.
• What is the maximum cable length supported by the TUSB551RWBR?
  The TUSB551RWBR 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 cable quality.
• Can I use the TUSB551RWBR in a USB 3.0 or USB 3.2 application?
  No, the TUSB551RWBR is a USB 2.0 repeater and is not compatible with USB 3.0 or USB 3.2. For USB 3.0 or USB 3.2 applications, use a repeater specifically designed for those speeds, such as the TUSB926.
• How do I power the TUSB551RWBR?
  The TUSB551RWBR can be powered from a 3.3V or 5V supply, and the recommended operating range is 3.0V to 5.5V. Ensure that the power supply is stable and can provide enough current to support the device and any downstream devices.
