How to use clock recovery component

[刘 洋]

I use the built-in routine [clock recover.osd] and want to compare the eye diagram before and after clock recovery, but the before and after eye diagrams have not changed, I don’t know how to adjust

Hello,
there is a difference between the input and the output due to the timing feature in the clock recovery component as shown in the attached image. The eye is centered at the 0.5 of the bit.

Hello,
In principle, there should be no difference to what has been used for the PAM example that we’ve exchanged eye traces of it. You need to make sure that you connect the clock recovery component in the same way explained in that example.
