I have an in-house developed board that uses a LMH0046 reclocker on the output of a LMH0030 serializer. After getting a series of jitter complaints, I rented a video analyzer and discovered that the LMH0046 is not reducing the jitter in the 100KHz range. It appears to be neutral at best. I then tested a third party reclocker product that uses the LMH0034 line equalizer followed by a LMH0046 reclocker (This arrangement is specifically described in the documentation). We inserted a jitter of 0.34UI and to our surprise, got a 0.34UI jitter out. The documentation clearly indicates that it should reduce a 0.75UI jitter to 0.05UI.
Does this part really work?
How do we interface the parts so that it does work?
