1. Intel Stratix 10 E-Tile Transceiver PHY Overview
UG-20056 | 2019.02.04
Channel bonding is a common technique used to minimize high speed serial lane-lane
transmit skew for multi-lane protocols. Channel bonding is supported under the
following conditions:
•
Using
• NRZ PMA direct mode
• Data rate limited to:
— 16-bit (parallel data width): 12.0 Gbps
— 20-bit (parallel data width): 16.0 Gbps
— 32-bit (parallel data width): 28.0 Gbps
Note: Bonding is only supported within a tile. Bonding is not supported within a package
across different tiles, even if the reference clock is shared.

1.4.4. Ethernet Hard IP (EHIP)

The Ethernet Hard IP is a hardened core of assorted multi-lane and single-lane
Ethernet components.
Intel Stratix 10 E-Tiles include four instances of the Ethernet Hard IP, which in turn
supports up to four multi-lane Ethernet MAC stacks, or 24 channels of single-lane
Ethernet channel (MAC/PCS) support.
