Notes:
1. PCB Capacitor specifications are listed in Table 3-3.
2. Total includes all capacitors for all supplies, except for the MGT supplies MGTAVCC and MGTAVTT, which are covered in
UG476
, 7 Series FPGAs GTX/GTH Transceivers User Guide and UG482, 7 Series FPGAs GTP Transceivers User Guide.
3. HRIO 47 µF capacitors can be consolidated at one 47 µF per four banks.
4. HPIO 47 µF capacitors can be consolidated at one 47 µF per four banks.
5. Decoupling capacitors cover down to approximately 100 Hz.
