Description

Pericom Semiconductor’s PI3VDP612, one to two Demux is

targeted for next generation digital video signals. This device

can be used to connect a Display Port Source to two Independent

Display Port Sinks.

The newly released Display Port spec requires a data rate of

2.7 Gbps with AC coupled I/Os. Pericom's solution has been

specifically designed around this standard and will support such

signals.

Application

Routing of Display Port signals with low signal attenuation be-

tween notebook DP connector and docking station DP connector.
