20G Active Retimer for USB 3.2

ANX7432 is a USB3.2 Gen2 20G active retimer capable of recovering the USB signals with loss compensation of up to 23dB. ANX7432 also integrates a mux to enable the following configurations: (Gen 1x2, Gen 2x1 and Gen 2x2) for USB Type-CTM (USB-CTM) applications. ANX7432 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 ANX7432 with built-in intelligent switching. With the intelligent digital switching, ANX7432 ensures the enhanced signals from the re-timers are preserved and outputted over the USB-C connector.

Main Features: 
Built-in re-timers
