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.
