CS1842 - Common Mode Filter with ESD Protection for HDMI and MIPI D-PHY Interface


  • High Common Mode Stop Band Attenuation:> 20 dB at 1 GHz
  • Large differential bandwidth > 2.5 GHz
  • ±15kV ESD protection per channel (IEC 61000-4-2Level 4, contact discharge)
  • Low Channel Input Capacitance Provides Superior Impedance Matching Performance
  • WDFN102.50mm×2.00mm×0.75mmpackage with0.50mmlead pitch
  • RoHS-compliant, Lead-free packaging
  • Device meets MSL 1 requirements


The CS1842 is a highly integrated Common Mode Filter (CMF) providing both ESD protection and EMI common mode noise filtering for systems using high speed differential serial interfaces, such as MIPI D-PHY or HDMI.

The CS1842 can protect and filter two differential line pairs in a small RoHS-compliant WDFN10 package, with cost and space savings over discrete solutions.


  • HDMI/DVI Display in Mobile Phones
  • MIPI D-PHY (CSI-2, DSI, etc) in Mobile Phones and Digital Still Cameras
