PRODUCT BRIEF

PI3DPX1207C

DP-Alt DP1.4/USB3.1 10Gbps Linear Redriver with Non-Blocking, Latency-Free and Built-in Aux Switch

PI3DPX1207C is the DP-Alt 1.4 (Max 10Gbps) Linear Redriver.

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 adjust-

ment by either pin or I2C control settings. It can optimize the DP/

USB 10Gbps signal performance over a variety of physical medi-

ums by reducing Inter-symbol interference jitters.

Since Linear Redriver does not block the Receiver DFE’s adaptive

channel controls, it can natively support DisplayPort Transparent

LT(Link Training).

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 ca-

pabilities to extend signal transmission features are ideal choice for

the 8-10Gbps high speed DP Alt signal integrity solutions.
