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.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Output 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
5. The outputs are measured one at a time with one transition per measurement.
