Four-Six-Eight-Channel EMI
Filter with Integrated ESD
Protection
The EMI520xMU Series are a 4, 6, 8−channel (C−R−C) Pi−style
EMI filter array with integrated ESD protection. Its typical component
values of R = 100 and C = 7 pF deliver a cutoff frequency of 250
MHz and stop band attenuation greater than 20 dB from 800 MHz to
5.0 GHz.
This performance makes the part ideal for parallel interfaces with
data rates up to 167 Mbps in applications where wireless interference
must be minimized. The specified attenuation range is very effective
in minimizing interference from 2G/3G, GPS, Bluetooth® and
WLAN signals.
The EMI520xMU Series is available in the low−profile 4, 6, 8−lead,
0.5mm thick UDFN packages with 0.4mm lead pitch.

Theory of Operation
From this it can be seen that a square wave consists of odd
order harmonics and to fully construct a square wave n must
go to infinity. However, to retain an acceptable portion of the
waveform, the first two terms are generally sufficient. These
two terms contain about 85% of the signal amplitude and
allow a reasonable square wave to be reconstructed.
Therefore, to reasonably pass a square wave of frequency x
the minimum filter bandwidth necessary is 3x. All
ON Semiconductor EMI filters are rated according to this
principle. Attempting to violate this principle will result in
significant rounding of the waveform and cause problems in
transmitting the correct data. For example, take the filter
with the response shown in Figure 4 and apply three
different data waveforms. To calculate these three different
frequencies, the 3 dB, 6 dB, and 9 dB bandwidths will be
used.
The EMI520x combines ESD protection and EMI
filtering conveniently into a small package for today’s size
constrained applications. The capacitance inherent to a
typical protection diode is utilized to provide the
capacitance value necessary to create the desired frequency
response based upon the series resistance in the filter. By
combining this functionality into one device, a large number
of discrete components are integrated into one small
package saving valuable board space and reducing BOM
count and cost in the application.
Application Example
The accepted practice for specifying bandwidth in a filter
is to use the 3 dB cutoff frequency. Utilizing points such as
the 6 dB or 9 dB cutoff frequencies results in signal
degradation in an application. This can be illustrated in an
application example. A typical application would include
EMI filtering of data lines in a camera or display interface.
In such an example it is important to first understand the
signal and its spectral content. By understanding these
things, an appropriate filter can be selected for the desired
application. A typical data signal is pattern of 1’s and 0’s
transmitted over a line in a form similar to a square wave.
The maximum frequency of such a signal would be the
pattern 1−0−1−0 such that for a signal with a data rate of
100 Mbps, the maximum frequency component would be
50 MHz. The next item to consider is the spectral content of
the signal, which can be understood with the Fourier series
approximation of a square wave, shown below in
Equations 1 and 2 in the Fourier series approximation.

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

the third harmonic term is significantly attenuated. This
serves to round the signal edges and skew the waveform, as
is shown in Figure 5b. In the case that a 100 MHz signal is
input to this filter, the third harmonic term is attenuated even
further and results in even more rounding of the signal edges
as is shown in Figure 5c. The result is the degradation of the
data being transmitted making the digital data (1’s and 0’s)
more difficult to discern. This does not include effects of
other components such as interconnect and other path losses
which could further serve to degrade the signal integrity.
While some filter products may specify the 6 dB or 9 dB
bandwidths, actually using these to calculate supported
frequencies (and corresponding data rates) results in
significant signal degradation. To ensure the best signal
integrity possible, it is best to use the 3 dB bandwidth to
calculate the achievable data rate.

Considering that 85% of the amplitude of the square is in
the first two terms of the Fourier series approximation most
of the signal content is at the fundamental (maximum
supported) frequency and the third harmonic frequency. If a
signal with a frequency of 33.33 MHz is input to this filter,
the first two terms are sufficiently passed such that the signal
is only mildly affected, as is shown in Figure 5a. If a signal
with a frequency of 66.67 MHz is input to this same filter,
