Can the TX of Transceiver-A be routed to the RX of Transceiver-A ext to the FPGA?

Hello,

This question is for both the Stratix II GX High Speed Serial Transceivers and the Stratix IV GX High Speed Serial Transceivers

Can the TX of Transceiver-A be routed to the RX of Transceiver-A external to the FPGA?

That is, is there any reason that an external loopback (off chip) cannot be done?

Are there any special considerations with going from Transceiver A back to A as opposed to going from A to B?

Thank you for your help,

    Hi Digitalone

    Though I don't know about this A/B issue(possibly you mean two channels) but I don't forsee any problems in connecting them externally(be it in a testbench model or actual hardware) as long as Rx receives good quality LVDS signal of correct speed from fellow Tx.

    Regards
