EMI9404 D

EMI9404
PRAETORIAN) III
4-Channel EMI Array with
ESD Protection
Description
The EMI9404 is an inductor−based (L−C) EMI filter array with
ESD protection, which integrates four filters in a UDFN package with
0.40 mm pitch. Each EMI filter channel of the EMI9404 is
implemented
with
the
component
value
of
1.8 pF−35 nH–4.7 pF−35 nH– 6 pF. The cut−off frequency at −3 dB
attenuation is 300 MHz and can be used in applications where the data
rates are as high as 160 Mbps, while providing greater than −35 dB
attenuation over the 800 MHz to 2.7 GHz frequency range. The parts
include ESD diodes on every I/O pin and provide a high level of
protection against electrostatic discharge (ESD). The ESD protection
diodes connected to the external filter ports are designed and
characterized to safely dissipate ESD strikes of ±14 kV, which is
beyond the maximum requirement of the IEC61000−4−2 international
standard.
This device is particularly well suited for wireless handsets, mobile
LCD modules and PDAs because of its small package format and
easy−to−use pin assignments. In particular, the EMI9404 is ideal for
EMI filtering and protecting data and control lines for the LCD display
and camera interface in mobile handsets.
The EMI9404 is housed in space saving, low profile, 0.40 mm pitch
UDFN packages in a RoHS compliant, Pb−Free format.

detail on TLP datasheet parameters, while application note
AND9006/D provides a more complete explanation of the
use of TLP for understanding protection product
characteristics.
Transmission Line Pulse (TLP) provides current versus
voltage (I−V) curves in which each data point is obtained
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 6. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
ESD capability because the 10s of amps current levels and
under 100 ns time scale match those of an ESD event. This
is illustrated in Figure 7 where an 8 kV IEC 61000−4−2
current waveform into a short is compared with TLP current
pulses at 8 A and 16 A, also into a short. A TLP I−V curve
shows the voltage at which the device turns on, as well as
how well the device clamps voltage over a range of current
levels. Typical TLP I−V curves for the EMI9404 are shown
in Figures 4 and 5 for positive and negative stress
respectively. Application note AND9007/D gives more
