Zynq-7000 PCB Design Guide www.xilinx.com 15UG933 (v1.8) November 7, 2014Chapter 3: Power Distribution SystemCapacitor SpecificationsThe electrical characteristics of the capacitors in Table 3-1 and Table 3-2 are specified inTable 3-3, and are followed by guidelines on acceptable substitutions. The equivalent seriesresistance (ESR) ranges specified for these capacitors can be over-ridden. However, thisrequires analysis of the resulting power distribution system impedance to ensure that noresonant impedance spikes result.FFG1156 Z-7100 1 0 0 1 1 1 1 0 0 1 1 1 1 1 1Notes:1.
