We see a transverse line in the image . Once appears keeps on appearing .
We are writing AD converted data into the frame memory and read data is output as HD-SDI .
Input = 1080i/59.94Hz
Working and finding :
We dont know why this is happening .
1. Phase Adjust Address 0x04 is set to 0x80 and when we see this issue if we change this value to say 0x90 we dont see this issue .
But this doesnt mean that by setting the Phase adjust to 0x90 from first ,we dont see this issue .
2.Auto Offset Address 0x1B is Disabled (use Manual offset ) and when we see this issue if we set Auto offset to Enable we dont see this issue .
3. As of now we dont see no relation ship between the temperature
But we see that there is change in the phase for the sampling clock when we change the temperature .
Please refer to the wave form and share your valuable advice .
With best regards and wishes
