TUSB1046-DCIRNQR is a 40-pin USB Type-C Alt Mode linear redriver and crosspoint switch for 10 Gbps USB 3.1 and 8.1 Gbps DisplayPort 1.4 HBR3 host-side designs.

Best for

  • Host-side USB Type-C ports requiring USB 3.1 Gen 2 and DisplayPort Alt Mode
  • Designs requiring 4-lane DisplayPort or USB plus 2-lane DisplayPort routing
  • Signal paths with PCB or cable insertion loss requiring linear equalization

Avoid if

  • An operating temperature outside 0°C to 70°C is required for this ordering variant
  • The application requires protocol-aware USB or DisplayPort retiming
  • The system cannot provide Type-C PD controller signals for mode and orientation control

Check before use

  • Verify 3.0 V to 3.6 V supply operation and local 0.1 µF decoupling at each power pin
  • Validate 90 Ω differential routing, pair matching, and channel insertion loss
  • Confirm GPIO or I2C mode configuration and the desired I2C address if I2C is used
