TS3USB31ERSER datasheet by Texas Instruments

TS3USB31ERSER Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS3USB31ERSER?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines.
• How do I ensure signal integrity with the TS3USB31ERSER?
  To ensure signal integrity, use a differential pair for the USB signals, keep the traces short and matched, and use a common mode filter or common mode choke to reduce electromagnetic interference (EMI).
• What is the maximum cable length supported by the TS3USB31ERSER?
  The TS3USB31ERSER supports cable lengths up to 3 meters, but this can vary depending on the specific application and cable quality. It's recommended to use high-quality cables and follow USB 3.0 specifications for cable length and signal integrity.
• How do I handle power management with the TS3USB31ERSER?
  The TS3USB31ERSER has a built-in power management feature that allows it to enter a low-power state when not in use. Additionally, the device can be powered down using the EN pin, and the VBUS pin can be used to detect the presence of a USB device.
• What is the ESD protection level of the TS3USB31ERSER?
  The TS3USB31ERSER has an ESD protection level of ±8 kV contact discharge and ±15 kV air gap discharge, which exceeds the USB 3.0 specification requirements.
