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 PbFree Package

1. Standard IEC 6100042 with CDischarge = 150 pF, RDischarge = 330, GND grounded.
2. These measurements performed with no external capacitor.
3. TVS devices are normally selected according to the working peak reverse voltage (VRWM), which should be equal or greater than the DC
or continuous peak operating voltage level.
4. VBR is measured at pulse test current IT.
