Electrical Design Considerations
This chapter describes the electrical interface details needed to design your carrier card to mate
with the Kria™ K26 SOM. The electrical interface design guidelines include the SOM connector
details and signal names, signal roung guidelines, and power supply design.
SOM Connector Overview
The K26 SOM uses two 240-pin connectors to provide electrical connecvity between the SOM
and the carrier card. These two connectors are referred to as SOM240_1 and SOM240_2.
The SOM240_1 and SOM240_2 connectors use the Samtec 0.635 mm AcceleRate HD high-
density 4-row, 60 posion connector set. The part number for the socket (ADF6–60–03.5–L–4–
2–A) is used on the boom side of the SOM. The part number for the terminal (ADM6–60–
01.5–L–4–2–A) is for use on the carrier card. The SOM240_1 and SOM240_2 connectors
provide support for following interfaces.
• Control and status signals
• Mulplexed I/O (MIO) bank
• PS-GTR high-speed serial transceiver signals
• High-performance I/O (HPIO) bank signals
• High-density I/O (HDIO) bank signals
• GTH high-speed serial transceiver signals
• Power system
Signal Naming Conventions
The SOM240 connectors adopt the naming convenons outlined in the following table.
