Description
Pericom’s PI3V713 is a 7-channel video mux/demux used
to switch between multiple VGA sources or end points. In a
notebook application where analog video signals are found in both
the notebook and the dock, a switch solution is required to switch
between the two video port locations. With the high bandwidth
of ~1.7GHz, the signal integrity will remain strong even through
the long FR4 trace between the notebook and the docking station.
In addition to high signal performance, the video signals are also
protected against high ESD with integrated diodes to V
DD
and
GND that will support up to12kV HBM ESD protection.
Application
Routing VGA signals with low signal attenuation and high ESD.
Applications
• Routes physical layer signals for high bandwidth digital video
• Monitor detection supports automatic switching

Description is TEST pin to enable TEST mode. IF this pin is LOW, then test
mode is enabled. For normal usage disable TEST mode by holding this pin
high, or floating. There is an internal 100Kohm pull-up on this pin
Control signal.
If MS pin is LOW, then this pin acts as a priority pin
If MS pin is HIGH, then this pin acts as a port select pin
If pin 30 is LOW, port 1 is chosen
If pin 30 is HIGH, port 2 is chosen Definition of chosen depends on the func-
tion of pin 30. For example, if the function is priority, then chosen means
"chosen as highest priority"

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the
switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little
propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the
switch and its interactions with the load on the driven side.
