The CSPEMI307A is a multichannel EMI/ESD array offering a combination of four low-pass filter + ESD channels to reduce EMI/RFI emissions on a data port and four dedicated ESD-only channels intended specifically for ESD protection on a USB port. 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 pistyle filters support bidirectional filtering, controlling EMI both to and from a data port connector.
