TUSB2046BIRHBTG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TUSB2046BIRHBTG4 to ensure optimal performance?
  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 together with a 90-ohm impedance.
• How do I handle the power sequencing for the TUSB2046BIRHBTG4?
  The VBUS pin should be powered up first, followed by the VCC pin. The VBUS pin should be powered down last to prevent backpowering the device.
• What is the maximum cable length supported by the TUSB2046BIRHBTG4?
  The maximum cable length supported is 3 meters, but this can be extended up to 5 meters with the use of active cables or repeaters.
• How do I implement the USB 2.0 high-speed data transmission with the TUSB2046BIRHBTG4?
  The device supports high-speed data transmission up to 480 Mbps. To implement high-speed transmission, the device should be configured in high-speed mode, and the USB 2.0 protocol should be followed.
• What is the recommended ESD protection for the TUSB2046BIRHBTG4?
  The device has built-in ESD protection, but additional external ESD protection devices can be used to further protect the device from electrostatic discharge.
