10G Active Mux (4x4) with Integrated Re-timers for U5B3.2/DisplayPortTM
Overview: 

ANX7451 is a 4x4 re-timing mux capable of switching DisplayPort (DP) and USB3.2 Gen 2 10Gbps signals to support a single USB Type-C™ (USB-C™) port. ANX7451 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. ANX7451 supports Separate Reference Clock Independent SSC (SRIS) and Bit-Level Re-timer (BLR) architectures for a hybrid implementation for Gen 1 and Gen 2. SRIS re-timers eliminate jitter transfer and guarantee Gen 2 high-speed operation. Host (source) and device (sink) applications are fully supported by ANX7451 with built-in intelligent switching. With the intelligent digital switching, ANX7451 ensures the enhanced signals from the retimers are preserved and outputted over the USB-C connector. ANX7451 integrates the local reference clock and SBU/AUX mux for switching DP AUX signals and reducing overall system BOM cost.
