The TUSB1042I is a redriving switch supporting USB 3.1 data rates up to 10 Gbps. The TUSB1042I provides several levels of receive linear equalization to compensate for inter-symbol interference (ISI) due to cable and board trace loss. The device operates on a single 3.3 V supply and comes in the industrial temperature range.

TUSB1042EVM is a functional board design of a linear redriver switch (TUSB1042) from a Type-C connector to a legacy Type B USB receptacle to connect to USB host systems using the TPS65982 controller for power delivery and CC pin control. The TUSB1042 equalization is easy to configure using the (...)
  • Plug and play design
  • Easy configurable though jumpers and switches
  • No external power through 5V DC IN is required
  • The TPS65982 is configurable though a SPI flash
