Hi all, for a video processing system I need to convert a 24-bit 4:4:4 parallel RGB signal to a composite video signal. I am using ADV7343 encoder for the conversion, with IMX6 Quad evaluation board which comes with a 24-bit parallel interface port. IMX6 port has only RGB pixel data (8 lines each), Clk, VSYNC, HSYNC, I2C and Data_Ready signals while the encoder has additional P_BLANK (for ED/HD blanking) and SFL pins. So how should we utilize these two additional pins ?  Should the SFL be connected for the correct functionality of encoder ?
