NUF8610MN Theory of Operation approximation of a square wave, shown below in The NUF8610MN combines ESD protection and EMI Equations 1 and 2 in the Fourier series approximation. filtering conveniently into a small package for today’s size From this it can be seen that a square wave consists of odd constrained applications. The capacitance inherent to a order harmonics and to fully construct a square wave n must typical protection diode is utilized to provide the go to infinity. However, to retain an acceptable portion of the capacitance value necessary to create the desired frequency waveform, the first two terms are generally sufficient. These response based upon the series resistance in the filter. By two terms contain about 85% of the signal amplitude and combining this functionality into one device, a large number allow a reasonable square wave to be reconstructed. of discrete components are integrated into one small Therefore, to reasonably pass a square wave of frequency x package saving valuable board space and reducing BOM the minimum filter bandwidth necessary is 3x. All count and cost in the application. ON Semiconductor EMI filters are rated according to this principle. Attempting to violate this principle will result in Application Example significant rounding of the waveform and cause problems in The accepted practice for specifying bandwidth in a filter transmitting the correct data. For example, take the filter is to use the 3 dB cutoff frequency. Utilizing points such as with the response shown in Figure 9 and apply three the 6 dB or 9 dB cutoff frequencies results in signal different data waveforms. To calculate these three different degradation in an application. This can be illustrated in an frequencies, the 3 dB, 6 dB, and 9 dB bandwidths will be application example. A typical application would include used. EMI filtering of data lines in a camera or display interface. In such an example it is important to first understand the Equation 1: signal and its spectral content.

The maximum frequency of such a signal would be the Equation 2 (simplified form of Equation 1): (cid:4) (cid:6) pattern 1-0-1-0 such that for a signal with a data rate of 100 Mbps, the maximum frequency component would be x(t)(cid:2)1(cid:3)2(cid:3) sin((cid:5)0t)(cid:3)sin(3(cid:5)0t)(cid:3)sin(5(cid:5)0t)(cid:3)(cid:7)(cid:7)(cid:7) (eq. 2) 2 1 3 5 50 MHz.

Filter Bandwidth From the above paragraphs it is shown that the maximum multiply the result by two). The following table gives the supported frequency of a waveform that can be passed bandwidth values and the corresponding maximum through the filter can be found by dividing the bandwidth by supported frequencies and the third harmonic frequencies. a factor of three (to obtain the corresponding data rate http://onsemi.com 4

This Bandwidth Maximum Supported Third Harmonic serves to round the signal edges and skew the waveform, as Frequency Frequency is shown in Figure 10b. In the case that a 100 MHz signal is 3 dB – 33.33 MHz (f1) 100 MHz input to this filter, the third harmonic term is attenuated even 100 MHz further and results in even more rounding of the signal edges 6 dB – 66.67 MHz (f2) 200 MHz as is shown in Figure 10c. The result is the degradation of the 200 MHz data being transmitted making the digital data (1’s and 0’s) 9 dB – 100 MHz (f3) 300 MHz more difficult to discern. This does not include effects of 300 MHz other components such as interconnect and other path losses which could further serve to degrade the signal integrity. Considering that 85% of the amplitude of the square is in While some filter products may specify the 6 dB or 9 dB the first two terms of the Fourier series approximation most bandwidths, actually using these to calculate supported of the signal content is at the fundamental (maximum frequencies (and corresponding data rates) results in supported) frequency and the third harmonic frequency.

To ensure the best signal signal with a frequency of 33.33 MHz is input to this filter, integrity possible, it is best to use the 3 dB bandwidth to the first two terms are sufficiently passed such that the signal calculate the achievable data rate. is only mildly affected, as is shown in Figure 10a.
