AMD Adaptive Computing is creating an environment where
employees, customers, and partners feel welcome and included.
To that end, we’re removing non-inclusive language from our
products and related collateral. We’ve launched an internal
initiative to remove language that could exclude people or
reinforce historical biases, including terms embedded in our
software and IPs. You may still find examples of non-inclusive
language in our older products as we work to make these
changes and align with evolving industry standards. Follow this
link for more information.

range from 480 Mbps to 84.48 Gbps
• Supports up to 16 consecutively bonded 7
series GTX/GTH, UltraScale™ GTH or UltraScale+
GTH transceivers and up to four bonded GTP
transceivers
• Aurora 8B/10B protocol specification v2.3
compliant
• Low resource cost (see Resource Utilization)
• Easy-to-use AXI4-Stream based framing (or
streaming) and flow control interfaces
• Automatically initializes and maintains the
channel
• Full-duplex or simplex operation
• 16-bit additive scrambler/descrambler
• 16-bit or 32-bit Cyclic Redundancy Check (CRC)
for user data
• Hot-plug logic
• Configurable DRP/INIT clock
• Single/Differential clocking option for
GTREFCLK and core INIT_CLK

Aurora 8B/10B v11.1 5
PG046 October 19, 2023
Chapter 1
Overview
This guide describes how to generate an AMD LogiCORE™ IP Aurora 8B/10B core using
AMD UltraScale™ and UltraScale+™ family GTH transceivers, AMD Kintex™ 7, Virtex™ 7
FPGA GTX and GTH transceivers, AMD Artix™ 7 FPGA GTP transceivers, and AMD Zynq™
7000 device GTX and GTP transceivers. The Aurora 8B/10B core supports the AMBA®
protocol AXI4-Stream user interface.
The AMD Vivado™ Design Suite produces source code for Aurora 8B/10B cores with a
configurable datapath width. The cores can be simplex or full-duplex, and feature one of
two simple user interfaces and optional flow control.
The Aurora 8B/10B core (Figure 1-1) is a scalable, lightweight, link-layer protocol for
high-speed serial communication. The protocol is open and can be implemented using
AMD FPGA technology. The protocol is typically used in applications requiring simple,
low-cost, high-rate, data channels and is used to transfer data between devices using one
or many transceivers.
