EMI2124
Single Pair Common Mode
Filter with ESD Protection
Description
The EMI2124 is an integrated common mode filter providing both
ESD protection and EMI filtering for high speed serial digital
interfaces such as USB2.0.
The EMI2124 provides EMI filtering for one differential data line
pair and ESD protection for one data pair plus USB ID pin. It provides
a separate Vbus line protection typically used for charging. 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 Data Lines ESD Protection to IEC61000-4-2 Level 4, ±12
kV Contact Discharge
• Provides VID & VBUS ESD Protection to IEC61000-4-2 Level 4,
±30 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
• 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
