7-series GTX issue

Jump to solution

Hello

 

I want to used 7-series transceiver IP example design to simulation, but txdata and rxdata is different.

 

Why does the txdata and rxdata is different?

 

Why does the rxdata into the frame check module can be check the txdata and rxdata is the same?

 

Have detail document to description frame check module?

 

Have any method can be check txdata and rxdata is the same?

Hi @quincyq2003,

 

From you waveform, txdata and rxdata are the same. You just  have to wait a bit to get the data on rxdataout:
