General Description

California Micro Devices’ CM1452 is a family of pi-style EMI filter arrays with ESD protection, which

integrates four, six and eight filters (C-L-C) in CSP form factor with 0.40mm pitch. Each EMI filter channel

of the CM1452 is implemented as a 3-pole L-C filter where the component values are 20pF-17nH-20pF.

The CM1452’s roll-off frequency at -6dB attenuation is 330MHz and can be used in applications where the

data rates are as high as 132Mbps while providing greater than 30dB over the 800MHz to 2.7GHz

frequency range. The parts include ESD diodes on every I/O 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 handsets, mobile LCD modules and PDAs because of its

small package format and easy-to-use pin assignments. In particular, the CM1452 is ideal for EMI filtering

and protecting data and control lines for the LCD display and camera interface in mobile handsets.

The CM1452 incorporates OptiGuard which results in improved reliability at assembly. The CM1452 is

available in a space saving, low profile Chip Scale Package with optional lead-free finishing

(95.5Sn/3.8Ag/0.7Cu). It is manufactured with a 0.40mm pitch and 0.25mm CSP solder ball to provide up

to 28% board space savings vs. competing CSP devices with 0.50mm pitch and 0.30mm CSP solder ball.
