Hello @quincyq2003,

 

In case of blue frame pointed in your post, you are actually sending 4-byte data on 2-byte internal datapath. So to accomplish this, TXUSRCLK2 frequency is half of TXUSRCLK frequency.

Ashish

Hi @quincyq2003

It is dependent on the TX_INT_DATAWIDTH (0 or 1).

Thanks,Vijay

Hello @vijayak

 

If interface width is 2-byte, then TX_INT_DATA_WIDTH=0.
