TS3USB221ERSER datasheet by Texas Instruments

TS3USB221ERSER Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS3USB221ERSER to minimize signal integrity issues?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the signal traces as short as possible. Additionally, it's recommended to use a common mode filter and to decouple the power supply with a 10uF capacitor.
• How do I ensure the TS3USB221ERSER is properly powered and what are the power sequencing requirements?
  The TS3USB221ERSER requires a single 1.8V to 3.3V power supply. It's recommended to power the device after the input signals are stable, and to ensure that the power supply is clean and free of noise.
• What is the maximum data rate supported by the TS3USB221ERSER?
  The TS3USB221ERSER supports data rates up to 5 Gbps, making it suitable for high-speed applications such as USB 3.0 and HDMI.
• How do I configure the TS3USB221ERSER for different applications, such as USB or HDMI?
  The TS3USB221ERSER can be configured for different applications by setting the appropriate pin configurations and using external resistors to set the output impedance. Refer to the datasheet and application notes for specific configuration details.
• What are the thermal management considerations for the TS3USB221ERSER?
  The TS3USB221ERSER has a maximum junction temperature of 150°C. To ensure reliable operation, it's recommended to keep the device temperature below 125°C. This can be achieved by using a heat sink, improving air flow, and reducing power consumption.
