Key Features

  • Flexible Type-C USB/DP combo re-driver supports four signaling combinations specified in USB Type-C and VESA DisplayPort Alt mode standards through either I2C target interface or ternary GPIO pins
  • Supports USB 3.1 Gen 1 data rate of 5 Gbps, and DisplayPort data rates at 1.62 Gbps, 2.7 Gbps and 5.4 Gbps (HBR2), AUX at 1 Mbps
  • Compliant: SuperSpeed USB 3.1 Gen 1 standard, DisplayPort v1.2 standard for DFP applications and VESA DisplayPort Alt mode on USB Type-C standard
  • Implements USB Type-C Safe state conditions on all connector facing pins
  • Configurable via ternary GPIO or I2C interface (operating up to 1 MHz)
  • Integrated termination resistors provide impedance matching on both transmit and receive sides
  • RX equalizers on all inputs to compensate for high-speed signal attenuation in PCB and cable channels
  • Active TX De-emphasis and Output swing on all outputs to assure high-frequency boost
  • Automatic receiver termination detection in USB 3.1 Gen 1 mode
  • Supports auto power saving modes during USB 3.1 Gen 1 operation
  • DP AUX sideband crossbar switch for Type-C plug orientation
  • DP AUX monitoring during DP link training to control DP TX output driver adjustment
  • Flow-through pinout to ease PCB layout and minimize crosstalk effects. Low crosstalk: DDNEXT < -45 dB at 2.7 GHz
  • Excellent Differential and Common return loss performance
  • Hot Plug capable
  • ESD HBM 8 kV CDM 1 kV on high-speed pins and HBM 4 kV CDM 500 V on control pins
  • Supports IEC61000-4-5 8/20 us ±16 V Surge test performance with external 4.7 Ω series resistors on the DRX1P/N, DRX2P/N and DAUXP/N pins
  • Operating temperature range -40 to +85 °C

Low Active Current Consumption

  • USB 3.1 Gen 1 only (Mode 1) active power: 115 mA (typ) for VOS = 1Vpp and DE=-3.5 dB
  • 2-lane DP HBR2 level 0 (Mode 3): 75 mA (Level 0: 400 mV with no Pre-emphasis)
  • 1-lane DP HBR2 level 0 (Mode 3): 38 mA (Level 0: 400 mV with no Pre-emphasis)
  • 4-lane DP only HBR2 level 0 (Mode 3): 150 mA
