California Micro Devices’ CM1693 is a family of pi-style EMI filter arrays with ESD protection, which integrates four or eight filters (C-L-C) into a small-form factor, uDFN 0.40mm 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 -6dB attenuation is 300MHz and can be used in applications where the data rates are as high as 140Mbps. The CM1693 also provides greater than -30dB attenuation over the 800MHz to 6GHz 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.

This device is particularly well suited for wireless handsets, mobile LCD modules and PDAs because of its small package format and easy-to-use pin assignments. In particular, the CM1693 is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in mobile handsets.

The CM1693 is housed in space saving, low profile, 0.40mm pitch uDFN packages in a RoHS compliant, lead-free format.
