EMI2121
Single Pair Common Mode
Filter with ESD Protection
Description
The EMI2121 is an integrated common mode filter providing both
ESD protection and EMI filtering for high speed serial digital
interfaces such as USB2.0.
The EMI2121 provides EMI filtering for one differential data line
pair and ESD protection for one data pair plus a supply input such as
USB2.0 Vbus or USB ID pin. It is supplied in a small RoHS-compliant
WDFN8 package.
Features
• Highly Integrated Common Mode Filter (CMF) with ESD Protection
provides protection and EMI Reduction for systems using high speed
Serial Data Lines with cost and space savings over Discrete Solutions
• Large Differential Mode Bandwidth with Cutoff Frequency > 2 GHz
• High Common Mode Stop Band Attenuation: >25 dB at 700 MHz,
>30 dB at 800 MHz Typical
• Provides ESD Protection to IEC61000-4-2 Level 4, ±12 kV Contact
Discharge
• Low Channel Input Capacitance provides Superior Impedance
Matching Performance
• Low Profile Package with Small Footprint in WDFN8 2.0 mm length
x 2.2 mm width x 0.75 mm height Pb−Free Package
http://www.DataSheet4U.net/
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Applications
• USB2.0 and other High Speed Differential Data Lines in Mobile
Phones and Digital Still Cameras
• MIPI D−PHY

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 8. 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 9 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 EMI2121 are shown in Figure 10.
