PI3V724

1 to 2 VGA Demux

Features

Description

ꢀÎFull VGA 1:2 demux with VSIS compliance

Pericom’s PI3V724 is a 7-channel video mux/demux used to

switch between multiple VGA sources or end points. In a note-

book 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 sta-

tion. In addition to high signal performance, the video signals are

also protected against high ESD with integrated diodes to VDD

and GND that will support up to +/-4kV contact ESD protection.

à R, G, B, Hsync, Vsync, DDC data, and DDC clk

channels are switched

ꢀÎIntegrated monitor detection circuit allows Automatic or

manual control

ꢀÎGenerates hot plug output signal to inform system when

monitor is present or not

ꢀÎDual Power Supply, 3.3V and 5V

ꢀÎIntegrated DDC level shiꢀer from 5V to 3.3V(bi-directional)

ꢀÎIntegrated 5V H/V output buﬀer with +/-24mA drive

In addition to switching, the product also integrates a monitor

detection feature. e monitor detection feature works indepen-

dently on each of the two outputs and allows automatic switching

as well as a self generated HPD signal that lets the system know

when a monitor is connected or disconnected.

ꢀÎESD tolerance on video I/O pins up to +/-4kV contact per

IEC61000-4-2 speciﬁcation

ꢀÎ-3dB BW of 1.7GHz (typ)

ꢀÎLow Xtalk, (-38dB typ)

ꢀÎLow and Flat ON-STATE resistance (Ron = 4-Ohm,

Ron(Flat) = 0.5ohm, typ)

ꢀÎLow input/output capacitance (Con = 5.6pF, typ)

ꢀÎPackaging (Pb-free and Green):

à 32-contact TQFN (ZL)
