    Hello,


    After checking on this, here's the connection guideline:

    • The proper connections are to connect "fboutclk" to "pll_fbclk" and to leave "hclk" open.

    Hope I've answered your query.


    Regard,

Thanks for the input.

I'm using only 2.5G so I need only one clock.

This is my Transceiver PLL component as generated by the IP wizard:

I have doubts about how to connect the following singals:

1. pll_fbclk (input)

2. fboutclk (output)

3. hclk (output)
