CSPEMI204 General Description
The CSPEMI204 is a low-pass filter array designed specifically to reduce EMI/RFI emissions and provide ESD protection for a headset port on cellular and mobile devices. The CSPEMI204 integrates two high quality, pi-style filters (C-R-C) filters, one for a microphone and one for an earpiece or speaker, each providing more than 30dB attenuation relative to the pass band attenuation in the 800-2700 MHz range. These filters support bidirectional filtering, reducing EMI both to and from the headset port and support bipolar audio signals without distortion.
In addition, the CSPEMI204 provides a very high level of protection for sensitive electronic components that may be subject to electrostatic discharge (ESD). The input pins can safely dissipate ESD strikes of ±8kV, 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 ±15kV. The CSPEMI204 protects sensitive components such as CPU and DSPs that have much weaker internal ESD protection circuitry usually only intended for mechanical handling protection.
The CSPEMI204 is particularly well suited for portable electronics because of its small package format and low weight. The CSPEMI204 is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing.
