CM1693: EMI Filter with ESD Protection

The CM1693 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six or eight filters (C-L-C) into a small-form factor, uDFN 0.40 mm pitch package. Each EMI filter channel is implemented as a 3-pole L-C filter, where the component values are 10pF-26nH-12pF. The CM1693's roll-off frequency at -6 dB attenuation is 300 MHz and can be used in applications where the data rates are as high as 140 Mbps. The CM1693 also provides greater than -30 dB attenuation over the 800 MHz to 6 GHz frequency range. The device includes ESD diodes on every pin that provide a very high level of protection for sensitive electronic components against possible electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±18kV, which is beyond the maximum requirement of the IEC61000-4-2 international standard.

Features
  • 700 MHz Attenuation, critical for LTE deployments
  • ±18kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)
Benefits
  • Suppressed EMI assists in improving handset performance in Total Isotropic Sensitivity testing, a requirement to get agency and carrier approvals
  • Protects against the most agressive ESD events
Applications
  • Camera and display interfaces, keypad interfaces
  • Emerging LTE and 4G protocols
End Products
  • Cellular phones, notebook computers, netbook computers, portable navigation devices
