Hello!I have some PLL issues with the AD9914. I used a 50M external reference clock, N=25, and finally got a 2.5G system clock. By programming, a single-frequency mode is used to generate a 400M sine wave. But soon, the waveform will be distorted. I think it may be a problem with the PLL losing lock. How to solve this problem?Thank you, look forward to your reply.
Are you using an evaluation board on this? If you do, kindly send to me the config file for the AD9914. If not, it would help if you would show us your board. Thanks.
