California Micro Devices&prime CM1693 is a family of pi-style EMI filter arrays with ESD protection, which integrates four and eight filters (C-L-C) in small form factor uDFN 0.40mm pitch packages. Each EMI filter channel on the CM1693 is implemented as a 3-pole L-C filter where the component values are 10pF-26nH-12pF. The CM1693&primes roll-off frequency at -6dB attenuation is 300MHz and can be used in applications where the data rates are as high as 140Mbps while providing greater than -30dB over the 800MHz to 6GHz frequency range. The parts include ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±18kV, 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.
