220.127.116.11. OTN Mode
The E-Tile Hard IP for Ethernet Intel FPGA IP supports OTN mode in 10/25G and 100G variants with optional RSFEC feature. It can support up to four OTN channels in 10/25G variant. This mode bypassed the Ethernet MAC and uses PCS66 interface to read and write to the PMA block.
- Alignment insertion—the TX PCS interface inserts alignment markers.
- Striper—enables logically sequential data to be segmented to increase data throughput.
The OTN RX datapath consists of an aligner block that enables the alignment of the incoming data.
