Functional Description
The CM1693-06DE is a pi-style EMI filter array with ESD
protection that integrates six 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-
06DE'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 CM1693-06DE also provides greater than -30dB
attenuation over the 800MHz to 6GHz frequency range.
The device includes ESD diodes on every pin which
provides 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 CM1693-06DE is ideal for EMI filtering and
protecting data and control lines for the LCD display and
camera interface in mobile handsetsl.
