Description

The PI3DPX1235Q is the USB Type-C DP-Alt DP 2.1 UHBR13.5/

USB 3.2 Gen 2 6:4 Linear ReDriver supporting DP Link-Training

Transparent for Source-side application. The device is compliant

to the VESA DP Alt 2.1 UHBR13.5 and USB 3.2 Gen 2 industry

standard.

Each of the DP 2.1 UHBR13.5 and USB 3.2 Gen 2 differential sig-

nals can be easily adjustable with equalization, output swing and

gain values by the I2C control setting. It can optimize the DP/USB

signal performance over a variety of physical mediums by reducing

Inter-symbol interference jitters.

Non-blocking Linear ReDriver provides better additive jitter per-

formance 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.
