Key Features

  • 2 bidirectional differential channel, 2 : 1 multiplex/demultiplexer switch, supports USB 3.1 Gen 1 specification (SuperSpeed only)
  • Compliant to SuperSpeed USB 3.1 Gen 1 standard
  • Pinout data flow matches USB Type-C connector pin assignments
  • Integrated termination resistors provide impedance matching on both transmit and receive sides
  • Automatic receiver termination detection
  • Flow-through pinout to ease PCB layout and minimize crosstalk effects
  • Compliant with JESD 78 Class II latch up test standard

Control Pins

  • Two control pins for each channel to select optimized signal conditions
  • Receive equalization on each channel to recover from InterSymbol Interference (ISI) and high-frequency losses, with provision to choose equalization gain settings per channel
  • Transmit de-emphasis on each channel delivers pre-compensation suited to channel conditions
  • Output swing adjustment
