i am using ADV7513  video driver in my design to get DVI output the register settig for this is taken care by 8051 CTRLLER through i2c. i am giving data to dvi from FPGA. hsync and vsync is given by FPGA seperately. i am not able to get sufficient information regarding DE pin.below mentioned are the registers i am configuring

fnADV7513Write(0x41,0x00);  //all circuits powered up
fnADV7513Write(0x98,0x03);
fnADV7513Write(0x9A,0xE0);
fnADV7513Write(0x9C,0x30);
fnADV7513Write(0x9D,0x01);
fnADV7513Write(0xA2,0xA4);
fnADV7513Write(0xA3,0xA4);
fnADV7513Write(0xE0,0xD0);
value1=Read_ADV7513(0xA2);
value1= Read_ADV7513(0x9A);
fnADV7513Write(0xF9,0x00);
fnADV7513Write(0x15,0x00);// Input RGB - 24 bits
fnADV7513Write(0x16,0x30);// 4:4:4,No color Depth,No Input Style,DDR Falling Edge
fnADV7513Write(0x17,0x00);// 4:3 aspect ratio
fnADV7513Write(0xAF,0x00);// DVI Output

attached file is my schematic of it. i am not able to get any output  on output lines my resolution is 1024*768 at clock speed of 65Mhz
