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.

4−ch. = 8−lead UDFN

•UDFN Package Size: 8−lead: 1.70 mm x 1.35 mm

•Increased Robustness Against Vertical Impacts During

Manufacturing Process

•These Devices are Pb−Free and are RoHS Compliant

•LCD and Camera Data Lines in Mobile Handsets

•I/O Port Protection for Mobile Handsets, Notebook

Computers, PDAs etc.

Transmission Line Pulse (TLP) Measurement

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

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.
