5G Active Mux (1x2) with Integrated Re-timer for USB 3.2
Overview:
ANX7421 is a USB3.2 Gen1 5G active mux with integrated re-timer capable of recovering the USB signals with loss compensation of up to 23dB. ANX7421 also integrates a mux (1x2) for USB Type-C™ (USB-C™) applications. ANX7421 supports Bit-Level Re-timer (BLR) architectures for Gen 1. Host (source) and device (sink) USB-C data-only applications are fully supported by ANX7421 with built-in intelligent switching. With the intelligent digital switching, ANX7421 ensures the enhanced signals from the re-timers are preserved and outputted over the USB-C connector.
