Intel Stratix 10 User Manual

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.

1.4.2. GXE Channel Usage
Channel usage depends on your channel configuration. In NRZ mode, all 24 GXE
channels in a tile are available. When the channel is configured in PAM4 mode and the
data rate is greater than 30 Gbps, two adjacent core interfaces are combined to
provide a single PAM4 channel.
Note: You can configure multiple data rates across different PAM4 channels < 30 Gbps
simultaneously.
