Hello Friends,
I need some help in my analysis of a problem listed below,
I am working on a product for a graphic application using an ADC with a
built-in PLL (clock for digitization of Video). During a vibration test on
the board we found out that the image shakes and we fixed everything we
suspected from loose cable to loose components with no success. Finally,
based on some expert advise.. I was told that the problem could be caused
due to mechanical stress on the loop filter capacitor which may be causing
the capacitance to change during vibration and thereby disrupting the PLL.
Has anyone faced similar issues? I would appreciate your expert feedback.
Thanks,
Girish
