We are developing a new automotive ADAS product, including a car front camera and electronic rearview mirror(E-mirror). Among the 60 prototypes producted recently, we found 5 of them have a strange
problem that the camera image flicker probabilistically. I tried to replace the camera, but this problem still exists. But when I add a coax cable between the camera and the E-mirror, the problem can be solved.
Attached pictures is S-parameter measurement waveforms of the camera and the E-mirror. I want to know what caused this problem and what should we do to completely solve this problem. Any suggestions
would be greatly appreciated! Thanks!
