TS3USB221ARSER datasheet by Texas Instruments

TS3USB221ARSER Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS3USB221ARSER 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 capacitors.
• How do I configure the TS3USB221ARSER for USB 3.2 Gen 2 operation?
  To configure the TS3USB221ARSER for USB 3.2 Gen 2 operation, set the MODE pin to logic high and the SPEED pin to logic low. Additionally, ensure that the device is powered from a 3.3V supply and that the VBUS pin is connected to the USB bus.
• What is the maximum cable length supported by the TS3USB221ARSER?
  The TS3USB221ARSER supports cable lengths up to 3 meters for USB 3.2 Gen 2 operation, and up to 5 meters for USB 2.0 operation. However, the actual cable length supported may vary depending on the specific application and cable quality.
• How do I implement overcurrent protection with the TS3USB221ARSER?
  The TS3USB221ARSER has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values should be chosen to set the overcurrent threshold to the desired value.
• What is the power consumption of the TS3USB221ARSER in idle mode?
  The power consumption of the TS3USB221ARSER in idle mode is typically around 10mA, but this can vary depending on the specific application and operating conditions.
