E-Tile XCVR PHY Gearbox 64/66 mode

Hello community, I would be interested on more details on the "Gearbox 64/66" mode of the E-Tile XCVR PHY IP https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_etile_...

Hi Laszlo,


Sorry for the late reply.


The parameter setting that you are interested with is called "PMA width" setting in "PMA interface" tab of the E-tile NativePHY IP.

  • Unfortunately I don't see 66 option here.
  • The only available option is 16, 20, 32, 40 and 64


However, there is very strict and complicated rule check implemented in E-tile NativePHY IP.

  • The IP will prompt error in system message console if user selected wrong combination of invalid setting.\
  • I highly encourage you to try out your desired setting directly in E-tile NativePHY IP to ensure it's valid combination of allowable setting


Thanks.
