产品特点 Features

High-speed channel processing

• Supports USB 3.0 specification (SuperSpeed only)
• Support of 2 channels
• Selectable receive equalization on each channel to recover from Inter Symbol 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 reliably work 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 will go 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

Enhancements
