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.

    Hi,
    
 
         Thanks for your valuable suggestions. I have come up with two ideas and I need your advise on implementing it. I want to know whether I could go ahead with the following methods or not.
    
 
    METHOD 1 :  Using one 32x16, one 16x8 crosspoint switch.
    
 
    
 
    NOTE : Aim is to feed 13 channels RGB (STANAG3350B) inputs and derive 3 RGB (STANAG3350B) outputs. Can you confirm whether this approach is correct or not?
    
 
    For ADV3203:
    
 
      
  
    1. “NC” represents  “No connection”.
      2. 
  
    2. 13 Red “R”, 13 Green “G” signals are fed to the ADV3203 which is 32 x 16 crosspoint switch.
      3. 
  
    3. The outputs are as follows : 3 Red signals and 3 green signals are taken as outputs.
      4. 
 
    
 
    For ADV3225:        
    
 
      
  
    1. “NC” represents  “No connection”.
      2. 
  
    2. 13 Blue “B” signals are fed to the ADV3225 which is 16 x 8 crosspoint switch.
      3. 
  
    3. The outputs are as follows : 3 Blue signals are taken as outputs.
      4. 
 
    
 
    ---------------------------------------------------------------------------------------------------------------------------------------------------------------
    
 
    METHOD 2 : Using three 16x8 crosspoint switch.
    
 
    
 
    NOTE : Aim is to feed 13 channels RGB (STANAG3350B) inputs and derive 3 RGB (STANAG3350B) outputs. Can you confirm whether this approach is also correct or not?

      3. 
  
    3. 13 Green “G” signals are fed to the 2nd ADV3225 which outputs 3 Green signals.
      4. 
  
    4. 13 Blue “B” signals are fed to the 3rd ADV3225 which outputs 3 Blue signals.
      5.
