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.

A1) Yes you can run all the same colors through one device

A2) Only the 3 channel parts are avaliable.

B) same answers as in part A

C) 1-13 analog buffer?  Other than a large array of op-amps with good…

Ah, I misunderstood the topology you wanted.  I though it needed to be 13x13 RGB which lead me to the 32x32 parts.

Both methods above will work for 13x3 RGB matrix switch.  I prefer method #2 since I like symmetry, both in parts and layout.  Cost would be about the same.
