Description
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 up to 27dB. Digital muxing (6×4) is supported by ANX7440 to ensure the enhanced signals from the re-timers 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.
Other key features
Built-in re-timers
+Integrated re-timers for USB 3.1 up to Gen 2 @ 10Gbps
+Integrated re-timers (Link training-tunable PHY repeater) for DisplayPort up to HBR3 @ 8.1Gbps. Supports both transparent mode and non-transparent mode (transparent or LTTPR).
+Loss compensation to recover up to 23dB channel loss (USB), up to 27dB (DP)
Integrated mux
+Integrated (6×4) mux switches USB and DP signals and preserves enhanced signal output over USB-C connector
+Mux control input through I2C commands from external I2C master (or, optionally through FLIP/OP_MODE pins)
+Integrated SBU/AUX mux for switching DisplayPort AUX +/- signals
Reference clock for re-timers
