2.4.1. Intel Agilex® 7 FPGA Packages Board-Level Decoupling Capacitors Summary
Table 12 shows the PCB recommended FPGA decoupling capacitor requirement for the Intel Agilex® 7 AGF006/AGF008 (small package size), Intel Agilex® 7 AGF012/AGF014 (medium package size), Intel Agilex® 7 AGI041/AGI040/AGI035/AGI027/AGI023/AGI022/AGI019, Intel Agilex® 7 AGF027/AGF023/AGF022/AGF019, and Intel Agilex® 7 AGM039/AGM032 large 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. Intel® plans to add more packages to Table 12 in the future release to address decoupling capacitors solutions for other Intel Agilex® 7 devices.
Decoupling capacitor recommendations for each tile is valid for any size of packages.
