The CSPEM I204 integrates two high quality, pi-style filters (C-R-C) filters, one for a micro- phone and one for an earpiece or speaker, each pro- viding 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 pr ovides a very high level of protection for sensitive electronic components that may be subject to electros tatic discharge (ESD). The CSPEMI204 can safely dissipate ESD strikes of ±8kV, the maximum requirement of the IEC 61000-4-2 inter- national standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides protection for contact dis- charges to greater than ±15kV. The CSPEMI204 pro- tects sensitive components such as CPU and DSPs that have much weaker inte rnal ESD protection cir- cuitry usually only intended for mechanical handling protection. The CSPEMI204 is particular ly well-suited for portable electronics because of it s small package format and low weight. The CSPEMI204 is available in a space- saving, low-profile Chip Scale Package with optional lead-free finishing.

Note 2: ESD applied to input and output pins with respect to GND, one at a time. Note 3: Clamping voltage is measured at the opposite side of the EM I filter to the ESD pin. For example, if ESD is applied to Pin A1, then clamping voltage is measured at Pin C1. Note 4: The parameters are guaranteed by design.
