1.5.1. GXE Transceiver Channel

The E-tile offers up to 24 full-duplex transceiver channels. These channels provide continuous data rates from 1 Gbps to 28.9 Gbps in NRZ mode, and 2 Gbps to 57.8 Gbps in PAM4 mode. For longer-reach backplane driving applications, adaptive equalization circuits are available to equalize the system losses.

The Physical Medium Attachment (PMA) provides interfacing capabilities to the following physical channels.

  • Transmitter (TX)
  • Receiver (RX)
  • High speed clocking resources

Within a tile, you can configure channels as both bonded and non-bonded in duplex operation. Nine reference clock pins drive mux logic that allows you to direct reference clocks (refclk_in_A and refclk_in_B) to the transmitter/receiver to enable these features. For more details about the reference clocks, refer to the Clock Network chapter.
