Tranceiver based switch

Question

Hi,Is there any way to retransmit data, received by tranceiver, around serialization/deserialization sequence? Basically, I need Serdes 3-port swicth functionality with a strict requirments on propagation delays in it. Therefore, best way to minimize them would probably be to switch the retimed data on a physical level before deserialization. Is there any way to do that using standart Altera or may be third-party components?

Hi MEmel1,Intel FPGA transceiver architecture is designed in a way where user can't bypass PMA block (that contains deserializer). User can only bypass the PCS block after the PMA.Attached is the high level block diagram for your reference. You can also find out more from XCVR user guide doc (chapter 5) in below linkhttps://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/arria-10/ug_arria10_xcvr_phy.pdfThanks.Regards,dlim
