16 years agoThe problem is solved. But another one has risen....
First the soulution: For other reasons, I had to change the frequency of my design from 100 to 120 MHz with 8b/10b coding. The data rate of the transceiver then has to be 3840 Mbps. This is the value which is to fill in the alt2gxb-megawizard field. Additionally, there must be enough free space for 8b/10b-coding which comes on top. the "real" data rate should be 4800 Mbps. Furthermore, I measured this with a serial data analyzer. The measured rate was 4976 Mbps, which is a multiple of my gxb reference clock of 155.52 MHz. The new problem is that I can see my data only after some reset-signals. For that problem I am going to open a new thread.
