Configurable transceiver enable

I need to enable transceiver channels in groups based on a board parameter read during board start-up. If the parameter is '0', channels 1 and 2 are enabled, channels 3 and 4 are disabled. If the par...

Hi Julia, 

 

Could you send back the information for the following clarifying questions to make sure the problem is fully understood and to avoid proposing the wrong solution.

  • Which Altera device family and part number are you using, and which transceiver type (e.g., FGT, FHT, GTS)?
  • Is the board parameter static for the entire power‑up, or can it change dynamically after FPGA configuration?
  • Do channels 1–2 and 3–4 operate at the same line rate and reference clock, or do they have different requirements?
  • Are these channels used for a specific protocol (e.g., PCIe, Ethernet, JESD204, Aurora), or are they raw PHYs?

    Hi JonWay,

    the device is Cyclone 10 GX 10CX105YU484I6G and the transceiver is the 12.5Gbps transceiver. Though I will use it at a lower data rate.

    The board parameter is static during the entire power-up. The channels operate at the same line rate and have the same reference clock. The channels will be used with a custom protocol, so raw PHYs are instantiated.

    Best regards,

    Julia
