Arria 10 GX Transceiver Native PHY using 64B/66B encoding/deconding in Basic(Enhanced PCS) Transceiver configuration rules.

As far as i know, when using Basic(Enhanced PCS)  Transceiver configuration rules, user has to do the 64B/66B encoding/deconding which is not included in IP core himself . So is there any example with 64B/66B encoding/deconding outside the Transceiver Native PHY using Basic(Enhanced PCS) ?

Hi,

 

I don't quite understand your question.

 

I can see the 64B/66B encoder/decoder feature is available in Enhance PCS mode as shown in user guide doc (page 60, table 24)

 

Thanks.

Hi,

Thank you for reply.

64B/66B encoder/decoder feature is available in Enhance PCS mode but not the Basic(Enhance PCS),10GBASE-R should be chosen. Please refer to the topic "Arria 10 GX Transceiver PHY will not configure to 64B/66B modes in Enhanced PCS mode", my question is similar with it.

If I have to choose the Basic(Enhance PCS) mode, is there any example with 64B/66B encoder/decoder or scrambler/descrambler outside the Transceiver Native PHY?

HI,

 

Sorry, I understand what you meant now.

 

As NativePHY 64b/66b encoder/decoder is mainly designed to compliance with 10GBASE-R protocol only, That's why the feature can't be enabled in Basic (Enhance PCS) mode. User can only enable it when selecting "10GBASE-R" preset in NativePHY IP.

 

We don't have 64b/66b encoder/decoder example design out of NativePHY IP as this normally will goes into some specific protocol IP solution offered by Intel FPGA (For instance : Ethernet IP or JESD IP).

 

In short, we sell the feature as part of certain IP solution rather than share it as example design.

 

Thanks.

HI,

 

I don't hear back from you after my feedback suggestion.

 

I hope my explanation is clear to you.

 

For now, I am setting this case to closure.

 

Thanks.
