PRELIMINARY INFORMATION, COMPANY CONFIDENTIAL
PI3V713
3.3V, 7-Channel Analog Video Switch
with Automatic Switching
Features
• Designed specifically to switch VGA signals
• 7-Channels for VGA signals (R,G,B, Hsync, Vsync, DDC
Data, and DDC CLK)
• Automatic or manual switching supported
–Forces re-read of EDID when automatically switching
• V_DD = 3.3V +/-10%
• DDC path will operate as a 5V to 3.3V level shifter
• H/V output buffer with +/-24mA drive
• ESD tolerance on video I/O pins is up to 12kV HBM per
JEDEC standard
• -3dB BW of 1.7GHz (typ)
• Low Xtalk, (-38dB typ)
• Low and Flat ON-STATE resistance (R_on = 4.8-Ohm,
R_on(Flat) = 0.5ohm, typ)
• Low input/output capacitance (Con = 5.6pF, typ)
• Packaging (Pb-free and Green):
–32-contact TQFN (ZLE)
Applications
• Routes physical layer signals for high bandwidth digital video
• Monitor detection supports automatic switching
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.
