can't configure internal data width 20bits when the data rate is 6Gbps

Hi,

 

I am using Vivado 13.4 for project with device virtex7-2000

 

i am trying to build simple transceiver with the following parameters: Linerate 6 Gpbs, refclk-300Mhz and internal/external data with 20 bits. no encoding.

 

When I set the line rate to 6 Gbps the data width options are:32, 40, 64, 80.

on lower frequency let's say up to 5 Gpbs, I got the options of 16, 20, 32, 40 , ....

 

According to your user guide I do have the option of internal data width of 20 bits when I am in 6 Gbps, so I don't know what is the problem

 

Can you help me? can you provide such an example to download?

 

Thanks

Shlomi

Hi

 

I was able to generate the transceiver with your required settings.

 

Have a look at the below snapshot.
