Product Description

California Micro Devices’ CM1690 is a family of pi-style

EMI filter arrays with ESD protection, which integrates

four, six and eight filters (C-L-C) in small form factor

uDFN 0.40mm pitch packages. Each EMI filter channel

of the CM1690 is implemented as a 3-pole L-C filter

where the component values are 16pF-12nH-16pF.

The CM1690's roll-off frequency at –6dB attenuation is

330MHz and can be used in applications where the

data rates are as high as 140Mbps while providing

greater than –35dB attenuation over the 1.0GHz to

3.0GHz 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

±15kV, beyond the maximum requirement of

the IEC61000-4-2 international standard. Using the

MIL-STD-883 (Method 3015) specification for Human

Body Model (HBM) ESD, the pins are protected for

contact discharges at greater than

±30kV.

This device is particularly well suited for wireless hand-

sets, mobile LCD modules and PDAs because of its

small package format and easy-to-use pin assign-

ments. In particular, the CM1690 is ideal for EMI filter-

ing and protecting data and control lines for the LCD

display and camera interface in mobile handsets.

The CM1690 is available in space saving, ultra low pro-

file 8-, 12-, and 16-lead 0.40mm uDFN packages with

lead-free finishing.
