Product Description

The  PI3V724 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 VDD and GND that will support up to +/-4kV contact ESD protection. In addition to switching, the product also integrates a monitor detection feature. The monitor detection feature works independently 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.


  • Full VGA 1:2 demux with VSIS compliance
    • R, G, B, Hsync, Vsync, DDC data, and DDC clk channels are switched
  • Integrated monitor detection circuit allows Automatic or manual control
  • Generates hot plug output signal to inform system when monitor is present or not
  • Dual Power Supply, 3.3V and 5V
  • Integrated DDC level shifter from 5V to 3.3V(bi-directional)
  • Integrated 5V H/V output buffer with +/-24mA drive
  • ESD tolerance on video I/O pins up to +/-4kV contact per IEC61000-4-2 specification
  • -3dB BW of 1.7GHz (typ)
  • Low Xtalk, (-38dB typ)
  • Low and Flat ON-STATE resistance (Ron = 4-Ohm, Ron(Flat) = 0.5ohm, typ)
  • Low input/output capacitance (Con = 5.6pF, typ)
  • Packaging (Pb-free and Green):
    • 32-contact TQFN (ZL)
