Intel Stratix 10 User Manual

B. PMA Direct PAM4 30 Gbps to 57.8 Gbps
Implementation
The PAM4 modulation scheme can help you achieve greater Ethernet speeds such as
200G/400G with efficiency and quality. Many protocol standards currently use the
PAM4 coding scheme, such as 400GBASE-SR16, 200GBASE-KR4, and 100GBASE-CR2.
The Intel Stratix 10 E-Tile found on TX devices features PAM4 capability to implement
these protocols.
This chapter introduces a design example using a PMA direct PAM4 57.8 Gbps 12-
channel design. The flow guides you through the following elements:
• Intel Quartus Prime Pro Edition IP instantiation
• Pin assignment
• Compilation
• Board bring up
• Debug tool introduction
B.1. Building Blocks and Considerations
Use the Intel Stratix 10 E-Tile Channel Placement Tool to configure 24 channels of
your PMA direct PAM4 30 Gbps to 57.8 Gbps design.
Start by selecting your protocols from Select Protocol(s) column. 24 channels of
PMA direct PAM4 30 Gbps to 57.8 Gbps designs use:
• 12 even PMA channels bonded out, all 24 channels instantiated
• 24 core interfaces
