High-speed channel processing

  • Supports USB 3.0 specification (SuperSpeed only)
  • Support of 2 channels
  • Selectable receive equalization on each channel to recover from InterSymbol Interference (ISI) and high-frequency losses, with provision to choose from five Equalization gain settings per channel
  • Selectable transmit de-emphasis and output swing on each channel delivers pre-compensation suited to channel conditions
  • Supports pin and I2C-bus programmable Input Signal Threshold setting to work reliably under different noise environments accommodating sensitivity needs
  • Integrated termination resistors provide impedance matching on both transmit and receive sides
  • Programmable termination resistor for receiver side
  • Automatic receiver termination indication and detection
  • Low active power: 330 mW/100 mA (typical), VDD = 3.3 V
  • Power-saving states:
    • 53 mW/16 mA (typical) when in U2/U3 states
    • 20 mW/6 mA (typical) when no connection detected
  • Excellent differential and common return loss performance
  • 14 dB differential and 15 dB common-mode return loss for 10 MHz to 1250 MHz
  • Flow-through pinout to ease PCB layout and minimize crosstalk effects
  • Hot Plug capable
  • Supports EasyCom that goes through the compliance testing controlled by the internal state machine
  • Power supply: VDD = 3.3 V ± 10 %
  • HVQFN24 4 mm  4 mm package, 0.5 mm pitch; exposed center pad for thermal relief and electrical ground
  • ESD: 5 kV HBM, 1250 V CDM
  • Operating temperature range 0 °C to 85 °C


  • Intelligent I2C-bus multiplexing and 5-level logic configuration options (with quinary pins),delivering ultimate flexibility
  • I2C-bus interface:
    • Standard-mode (100 kbit/s) or Fast-mode (400 kbit/s)
    • 3.3 V tolerant
