LVDS Signal Jitter - Cable Length and Data Rate

Posted Feb 17th 2012

Question:

Your design has some LVDS serializers and deserializers that send high-speed data over a serial data link. Your colleagues are concerned about signal jitter; and they would like to know how cable length and data rate effect jitter. What do you think will have more of an effect on your signal jitter, cable length or data rate?

Answer:

For this analysis, we will consider the MAX9207/MAX9208 devices. A study was performed that tested these devices from 450 to 750 Mbps. These devices were tested on cables ranging from 5 ft to 60 ft. The study shows that cable length had a more significant impact on signal jitter than the changes in data rate.
