crosspoint switch

I want to feed 12 channels of RGB signals, 1 Y/C signal (i.e.) 38 signals as input to crosspoint switch. The available crosspoint switch (ADV3201) supports only 32 inputs : 32 outputs. I want to derive 2 outputs from any input channels that I want without any limitation. So kindly suggest me Analog devices parts to implement my logic.

  • Thanks a lot for your support. Your suggestions did resolve my issues and provided me a feasible solution!

    I have few queries regarding :

    A) Triple Differential Receiver AD8145 

    B) Triple Differential Driver AD8146

    C)  1 differential signal to 13 differential signal

    A : Problem description of AD8145 :

    My aim is to convert the Differential RGB(STANAG3350B) signals to single ended RGB(STANAG3350B) signals. You know that I am grouping my Red signals, Green signals, Blue signals of all channels.  Consider that I have 3 Red signals , 3 green signals and 3 blue signals which I want to convert to single ended signal using this IC. Hence I have to use 3 such ICs.

    1. Can I connect all my 3 Red signals to the 1st IC, 3 blue signals to my 2nd IC, 3 green signals to my 3rd IC?

    2. This IC supports only 3 differential inputs. Can you suggest me an IC which supports more than 3 differential inputs for the same application?

    B : Problem description of AD8146 :  (This problem is the vice-versa of above problem description)
