1 / 14 page 1 www.pericom.com 10/22/14 Description 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. In addition to switching, the product also integrates a monitor detection feature. The 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. Features Î Î Full VGA 1:2 demux with VSIS compliance à R, G, B, Hsync, Vsync, DDC data, and DDC clk channels are switched Î Î Integrated monitor detection circuit allows Automatic or manual control Î Î Generates hot plug output signal to inform system when monitor is present or not Î Î Dual Power Supply, 3.3V and 5V Î Î Integrated DDC level shifter from 5V to 3.3V(bi-directional) Î Î Integrated 5V H/V output buffer with +/-24mA drive Î Î ESD tolerance on video I/O pins up to +/-4kV contact per IEC61000-4-2 specification Î Î -3dB BW of 1.7GHz (typ) Î Î Low Xtalk, (-38dB typ) Î Î Low and Flat ON-STATE resistance (Ron = 4-Ohm, Ron(Flat) = 0.5ohm, typ) Î Î Low input/output capacitance (Con = 5.6pF, typ) Î Î Packaging (Pb-free and Green): à 32-contact TQFN (ZL) Pin Diagram GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 32 31 30 29 28 R G GND VDD B H_SOURCE V_SOURCE MS SDA_SOURCE SCL_SOURCE Rref R1 R2 G1 G2 VDD B1 B2 H1_OUT H2_OUT V1_OUT V2_OUT PI3V724 1 to 2 VGA Demux 14-0168 |
