66AK2H14: Hyperlink Interface between SOCs

Madhu Sharma

Part Number: 66AK2H14

Hi,

In my design, i am planning to use two hyperlink interfaces of a 66AK2H14 to connect to two different 66AK2H14 devices present on same board.

The external data received from SRIO will be processed and sent over Hyperlink to other SOCs.

So I need both the hyperlink interfaces to be operated at a time, with full 10Gbps data-rate.

Please let me know, whether this is possible.

Also please let me know if there is any limitation on operating both hyperlink interfaces at a time.

Regards,

Madhu.

Hi Madhu,

I've forwarded this to the hyperlink experts. Their feedback should be posted here.

Hi,

It is possible to run Hyperlink at 10G x 4 lanes = 40G baud rate on K2H device. Also, the two Hyperlink ports are independent you can use them at the same time.

Hi Eric,

Thanks for the reply.

When two ports of hyperlinks operating at a time is considered, Is there any known issues or workarounds to be taken care before the design?

Regards,

Madhu.
