system every other clock cycle for a resulting frequency of 50 mhz the third line 406 on the graph in fig4 shows the bit pattern u201c 0100100100 u201d inputting energy every third clock cycle with the bit pattern energy is input to the system at 33 mhz the fourth line 408 on the graph in fig4 shows a bit pattern with a binary one every fourth clock cycle inputting energy at 25 mhz the fifth signal 410 on the graph in fig4 shows a different 25 mhz signal the bit pattern is u201c 0011 u201d and the bit pattern duty cycle is 50 bit patterns with a 50 duty cycle have the strongest effect in inciting power supply resonance if any of the frequencies generated by a particular bit pattern matches the power supply resonance frequency of the ic the ic may malfunction data to be transmitted between integrated circuits passes through high power transmission amplifiers before being transmitted from one integrated circuit to another these signals are greatly amplified on an integrated circuit and may have a relatively large effect on a power distribution network if a frequency of data transmitted between integrated circuits occurs at a power supply resonance frequency the power distribution network may excite the power supply impedance spike.
