For optimal performance, it is recommended to follow the PCB layout and routing guidelines provided in the TUSB7340 application note (SLUA623) and the High-Speed USB Layout Guidelines (SLIT634). This includes using a solid ground plane, minimizing trace lengths, and avoiding vias and right-angle turns.
To ensure EMI compliance, follow the EMI mitigation guidelines in the TUSB7340 application note (SLUA623). This includes using a shielded cable, minimizing loop areas, and using EMI filters or common-mode chokes. Additionally, ensure that the system meets the requirements of the relevant EMI standards, such as FCC Part 15 or EN 301 489-17.
The TUSB7340 has a maximum junction temperature of 150°C. To ensure reliable operation, it is recommended to keep the device temperature below 125°C. This can be achieved by using a heat sink, ensuring good airflow, and minimizing power consumption. Refer to the thermal management guidelines in the TUSB7340 datasheet and application note (SLUA623).
The TUSB7340 requires a 3.3V power supply. It is recommended to use a low-dropout linear regulator (LDO) or a switching regulator to ensure a stable and regulated power supply. Additionally, consider using power sequencing and voltage monitoring to ensure proper power-up and power-down sequences.
When using the TUSB7340 in a USB 3.0 application, ensure that the system meets the USB 3.0 specification requirements, including signal integrity, jitter, and eye diagram requirements. Additionally, consider using a USB 3.0 redriver or repeater to extend the cable length and improve signal quality.
