PRODUCT BRIEF
PI3DPX1205A
DP-Alt DP1.4/USB3.1 10Gbps Type-C Linear ReDriver Mux with Latency-free and built-in Aux/SBU Mux
PI3DPX1205A is the DP-Alt 1.4 (Max 10Gbps) 6:4 Active Mux Lin-
ear 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 val-
ues by the pin/ 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 2x better additive jitter
performance than the other conventional CMOS ReDriver. Lin-
ear 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.
This non-blocking linear redriver is named as “Trace Loss Can-
cel-ing” technology, and supports the cascading connections be-
tween Host and Device high speed link. It means multiple Linear
Redriver can be placed any locations to work seamlessly to com-
pensate high insertion loss.
