Virtex 5: using IODELAY with ISERDES and monitoring

Jump to solution

Hi,

Device: Virtex-5

I would like to use the output of IODELAY instance for internal logic (monitoring etc..)  and ISERDES instance at the same time.

Is this routing scheme allowed ?

 

Regards,

Kimmo

Hi Pthakare,
Thanks for your reply.
Data rate: 320 Mbps
I tried to use the following schemes shown in the figure below. The version #3 seems to be working.

Hi @kimmoj

 

The Delayed data (Data_out)  Destination from the IDELAY can be  ILogic/ISERDES/Fabric .

But I am not sure and I would like to check at my end if data_out from the IDELAY can be used in fabric as well as routed to ISERDES.

Meanwhile can you also try and let us know your observations ?

Also what is the data rate incoming data signal ?

For the reliable registering  of data in the fabric , you also need to consider the maximum Supported frequency

in the Virtex-5 fabric.
