10G Active Mux (6x4) with Integrated Re-timers for USB 3.1/DisplayPort.
Overview: 

ANX7440 is a re-timing mux capable of switching DisplayPort (DP) and USB 3.1 Gen 2 10Gbps signals to support a single USB Type-C™ (USB-C™) port. ANX7440 has built-in re-timers to recover both the USB and DP signals with loss compensation of 23dB for USB and up to 27dB for DP. ANX7440 supports Separate Reference Clock Independent SSC (SRIS) and Bit-Level Retimer (BLR) architectures for a hybrid implementation for Gen 1 and Gen 2. SRIS re-timers eliminate jitter transfer and guarantee Gen 2 operation. Digital muxing (6x4) is supported by ANX7440 to ensure the enhanced signals from the retimers are preserved and outputted over the USB-C connector. ANX7440 integrates the SBU/AUX mux for switching DP AUX signals and reducing overall system BOM cost

The ANX7440 can be adopted by Intel, AMD, Qualcomm, MTK platform designs.

Main Features: 
  • Built-in re-timers
    • Integrated re-timers for USB 3.1 up to Gen 2 @ 10Gbps
    • Supports both Separate Reference Clock Independent SSC (SRIS) and Bit-Level Re-timer (BLR) Architectures of USB3.1 Specification (Appendix-E)
