iBERT CPRI

Hi,

 

I am testing the GTP with iBERT. Near-end PCS loopback works, but not

near-end PMA. Any clues?

 

Also my CLKIN is 122.8 but the TXUSRCLK2 is 115.22 i.e. (15/16)*CLKIN,

why?

 

Regards,

e

How does the IBERT compute the TXUSRCLK and TXUSRCLK2?

 

Can I control the parameters of the PLL and DCM for TXUSRCLK and TXUSRCLK2?

Via UCF maybe?
