Dear All,

I wish to build an RGBS to Composite and S-Video using BH7236AF and also using the THS7374 AMP. I have created the design below:

However when I test the circuit on my Sega the composite output is like below:

Can someone help me out on this? Also, the output if the THS7374 is also not upto the mark... :( I dont know what is wrong...

If someone can verify my circuit and provide me the solution, I am in dire need of help! :(

Kind Regards,
Rama
 
I'm not familiar with the chip, I use the CXA2075.
 
Why not use the datasheet example?

I realized later that the Subcarrier signal was not connected! hence the messed up colors...:(
 
Why are you using a THS if the main chip already has RGB Passthrough?
