EMI4183
Common Mode Filter with
ESD Protection
Functional Description
The EMI4183 is an integrated common mode filter providing both
ESD protection and EMI filtering for high speed digital serial
interfaces such as MIPI D-PHY.
The EMI4183 provides protection for three differential data line
pairs in a small RoHS-compliant WDFN16 package.

Transmission Line Pulse (TLP) Measurements
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 11. TLP I-V curves of ESD protection devices accurately demonstrate the product’s ESD capability because the 10 s
of amps current levels and under 100 ns time scale match those of an ESD event. This is illustrated in Figure 12 where an 8 kV
IEC61000-4-2 current waveform is compared with TLP current pulses at 8 and 16 A. A TLP 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 EMI4183 are shown in Figure 13.
