Please see the image of noise. When they use this device for XGA, SXGA (aspect ratio 4:3 or 5:4) and WXGA(1280*768), there is no issue. Do you have any idea of … RE: AD9884AKSZ-140 noise issueForum ReplyVideo02 August, 2018This question has been assumed as answered either offline via email or with a multi-part answer.

Customer said there is no noise on the analog input. They changed the signal source, there was 4*4 mm lattice noise with 1280*720(DOTCLOCK:74.25MHz) input signal. You are unable to duplicate the test, so … RE: AD9884AKSZ-140 noise issueForum ReplyVideo11 June, 2018OK, seems PLL filter loop is stable. The AD9884 is an old part and I have not heard of this problem before. With the fact that this moire pattern becomes more pronounced with low amplitude, it would suggest that noise is getting injected on the analog inputs. I am unable … RE: AD9884AKSZ-140 noise issueForum ReplyVideo11 June, 2018Customer did the test but there were no difference. They said that as a picture, it displays normally but lattice noise of 4 mm square is superimposed on the lower bit. And in the lattice noise becomes easy to see with the low signal level. Also, by lowering the R … RE: AD9884AKSZ-140 noise issueForum ReplyVideo07 June, 2018The part should work fine for this format (720p). Let's try a strange test, with one finger touching a ground on the board, with another finger touch the caps that are part of the PLL filter and see if the moire pattern changes. What you are doing changing the … RE: AD9884AKSZ-140 noise issueForum ReplyVideo07 June, 2018Thank you for your advice. The board rayout is same. There is no difference with hardware and customer has just changed the software. Is AD9884AKSZ-140 are not suitable for 1280*720(DOTCLOCK: 74.25MHz) ? RE: AD9884AKSZ-140 noise issueForum ReplyVideo06 June, 2018For the noise are you talking about the moire like pattern. It is very hard to assess noise when the image is highly compressed like jpeg images. Without a better image to look at it's hard to tell the noise source. Often noise in analog video systems can be … <<<1>>>
