2.4.1. Agilex™ 5 FPGA Packages Board-Level Decoupling Capacitors Summary
The following table shows the PCB recommended FPGA decoupling capacitor requirement for the Agilex™ 5 device packages.
Fabric or core decoupling capacitors are highly dependent on the size of the core or fabric (LE and number of GPIO pins) in the package.
