ADV7513 video output issues.


what am I trying to do?

Want to convert RGB 24 bit (External DE,Vsync and Hsync) to HDMI.

I am sending a 800 x 480 video through RGB input of ADV 7513.

Below are the i2c settings.


                HDMI_Write(0x41,0x10); // Power Up Transmitter










                //Setup Video Input Mode

                HDMI_Write(0x15,0xF0); //Video Format ID (24 bit RGB 4:4:4 or YCbCr 4:4:4 Separate Syncs) and I2S frequency Invalid

                HDMI_Write(0x16,0x30); //Input Color depth (8 bit)

                HDMI_Write(0x17,0x00); //Aspect ratio of input Video (Set for 4:3 but ours is 3:2)


                //Setup Video Output Mode

                HDMI_Write(0x18,0x46); //CSC Disable

                HDMI_Write(0xAF,0x06); //HDMI Mode Select


After configuring this.i tried reading video mode detection registers

Progressive mode information--------->case 1:240 P and 263 lines
