Each EMI/RFI channel integrates a high quality pi-style filter (C-R-C) which provides greater than 30dB attenuation in the 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a data port connector. The CSPEMI307A provides a high-level of ESD protec- tion on all eight channels for sensitive electronic com- ponents that may be subjected to electrostatic discharge (ESD). The input pins are designed and characterized to safely dissipate ESD strikes of 15kV, exceeding the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD- 883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides protection for contact discharges to greater than 30kV. The CSPEMI307A is particularly well suited for porta- ble electronics (e.g., cellular telephones, PDAs, note- book computers) because of its small package footprint and low weight. The CSPEMI307A is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.
