I am extracting the Composite sync by using EL1881 and the extracted composite sync is applied to AD725 Hsync input pin.
By using AD725 i am generating composite video output and S-Video output (by separate chips )from individual RGB sources.
In composite video output case, receiving the proper output,
But S-Video output case, there is no proper output its randomly coming and going.
Please suggest the extracted composite sync is applied to AD725 Hsync pin is correct or not.
