    • LSTX and LSRX snooping
    • I2C register based Flat gain and linearity control
    • Peaking gain of +20 dB at 10 GHz
  • Supports USB 3.2 Gen1x1, Gen 1x2, Gen2x1, Gen2x2 (5 Gbps and 10 Gbps)
    • I2C register based Flat gain and linearity control
    • Peaking gain of +12.1 dB at 5 GHz
  • Supports DisplayPort link rates at 1.62 Gbps (RBR), 2.7 Gbps (HBR), 5.4 Gbps (HBR2), 8.1 Gbps (HBR3) and DP 2.0 UHBR3 targeted - pending compliance
    • DP AUX monitoring during DP link training to control DP channel
    • I2C register based Flat gain and linearity control
    • Peaking gain of +10.2 dB at 4.05 GHz
  • Compliant to DP1.4, Thunderbolt3 and USB4, USB3.2 standard and USB Type-C Alt mode interoperability testing
  • Configurable via I2C interface with a configurable address pin
  • Integrated termination resistors provide impedance matching on both transmit and receive sides
  • Autonomous orientation detection of USB-C connection and its configurable enable control
  • Supports maximum voltage limit (Vvoltage_jump) to align to the latest USB3 specification and computing platform capabilities
  • RX equalizers on all high-speed inputs to compensate for signal attenuation
  • Automatic receiver termination detection in USB 3.2 and USB4 modes
  • Good linearity over the frequency band (50 MHz to 10.3 GHz) and voltage dynamic range
  • Excellent differential return loss performance
  • Flow-through pin-out to ease PCB layout and minimize crosstalk effects
