DP-Alt DP1.4/USB3.1 10Gbps Type-C Linear ReDriver Mux with Latency-free Aux listening and DCI


PI3DPX1205A1 is the USB Type-C DP-Alt DP1.4/USB3.1 Gen2 6:4 Linear Redriver supporting DP Link-Training Transparent for Source-side application. The device is compliant to the VESA DP Alt 1.4 and USB 3.1 Gen 2 industry standard.

Each of the DP1.4 and USB3.1 Gen2 differential signals can be easily adjustable with equalization, output swing and gain values by the I2C control setting. It can optimize the DP/USB 10Gbps signal performance over a variety of physical mediums by reducing Inter-symbol interference jitters.

Non-blocking Linear Redriver provides better additive jitter performance than the conventional CMOS Limiting ReDriver. Linear Equalization does not block the Receiver DFE’s adaptive channel controls, supporting DisplayPort Transparent LT(Link Training) without dependency of the DP-Aux channels listener.
