Wireless handsets Handheld PCs/PDAs LCD and camera modules Lead-free version available 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 ES...
