The CM1452 family of pi-style EMI filter arrays with ESD protection, 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 roll-off frequency at -6dB attenuation is 330MHz and can be used in applications where the data rates are as high as 132Mbps and provide greater than 30dB over the 800MHz to 2.7GHz frequency range. The ESD diodes on every I/O pin provide a very high level of ESD protection for sensitive electronic components. The ESD protection diodes connected to the filter port 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.
