3.3V 10Gbps USB Type-C® DP-Alt Linear Redriver with AUX/SBU mux switch and AUX Listener


PI3DPX1207B1 is the DP-Alt 1.4 (Max 10Gbps) Linear RedriverTM. DP1.4 standard can support 4K2K@120Hz / 25.82 Gbps with 4-channels.

Each of the DP1.4 and USB3.1 Gen2 differential signals can be easily adjustable with equalization, output swing and gain adjustment by either pin or I2C control settings. 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 can provides 2x better additive jitter performance than the conventional CMOS-based Redriver.
Since Linear Redriver does not block the Receiver DFE’s adaptive channel controls, it can natively support DisplayPort Transparent LT(Link Training) without any dependency of the DP-Aux channels listener.

Named as “Trace Loss Canceling” technology, and supports the cascading high speed link connections between Host and Device. It means multiple linear Redriver can be placed in the link to work seamlessly to compensate high insertion loss.

The Cascading, Low Jitter and Simplicity of Gain adjustment capabilities to extend signal transmission features are ideal choice for the 8-10Gbps high speed DP Alt signal integrity solutions.
