Other Parts Discussed in Thread: TVP5158, TVP5150, TVP5150AM1
the previous design made use of TVP5158, now TVP5150AM1-EP is used, compared the datasheet, TVPS5158 seems have stonger capability to filter noise,see section 3.6, there are 5CH~5Fh registers to set noise reduction:Max noise level can be set,color killer can be set,noise filter BEta can be set. while TVP5150,only color killer can be set,my question is:
1. is the noise filtering capability of TVP5150 weaker than TVP5158?
2.is there additional register to set noise filter for TVP5150?
3.in my TVP5150 application, CVBS from CCD is transmitted to TVP 5150+DSP+LCD, but the SW engineer found that the the first frame of YUV data on the same static image are hugely different from next frame(second, third,...), but for TVP5158, it doesn't has this problem, so could you help troubleshoot this problem?
by the way, the analog and digital ground are the same pannel without isolation, is it allowed?
