20G Active Mux (2x2) with Integrated Re-timer and CC Detection for USB 3.2

ANX7434 is a USB 3.2 Gen 2 20G active mux with integrated re-timer and CC Detection capable of recovering the USB signals with loss compensation of up to 23dB. ANX7434 specifically supports Gen 2x2 for USB Type-CTM (USB-CTM) applications. ANX7434 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 operation. Host (source) and device (sink) USB-C data-only applications are fully supported by ANX7434. With the integrated SRIS re-timer function and x2 USB support, ANX7434 ensures the enhanced signals from the re-timers are preserved and outputted over the USB-C connector.
