Hi All,

I am planing to use an RGB to CVBS encoder (ADV7343) to get 24-bit pixel bus line to above analog signal form. I am using IMX6 application processor for this task, and can someone direct me to a source where I can find timing parameters of this standard ?

This is an example of an entry I have in lcd file :

{
/* 720x480@ 57 Hz , pixel clk @ 27MHz*/
"MY-LCD", 57, 720, 480, 30000, 40, 60, 10, 10, 20, 10,
FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
FB_VMODE_NONINTERLACED,
0,},
{

I specifically need hback-porch, hfront-porch, vback-porch, vfront-porch, hsync-len, vsync-len timing parameters for above video standard !

Thanks in Advance
