» Product Change Notification
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   Benefits
     
  • 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
  
  • Integration of ESD and Filter function
  • Large Differential Mode Bandwidth with Cutoff Frequency > 2 GHz
  
  • Rejects cellular transmit frequencies
  • High Common Mode Stop Band Attenuation: >25 dB at 700 MHz,
    >30 dB at 800 MHz Typical
  
  • Rejects cellular transmit frequencies
  • Provides ESD Protection to IEC61000-4-2 Level 4, 12 kV Contact Discharge
  
  • High level ESD protection
  • Low Channel Input Capacitance Provides Superior Impedance Matching
 
  • Low capacitive loading
Applications
  • USB2.0 and other High Speed Differential Data Lines in Mobile Phones and Digital Still Cameras
  • MIPI DPHY
