California Micro Devices announces two application specific integrated passive (ASIP) devices integrating highly effective electromagnetic interference (EMI) filtering and robust electrostatic discharge (ESD) protection to support microphone and speaker applications for wireless handsets and PDAs. The CSPEMI204 address the low-cost architecture segment of the wireless handset markety where single channel audio ports are a key feature. The device provides EMI filtering with ESD protection for both a single channel microphone port and a single channel speaker port within a single CSP device. The CSPEMI205 provides a single chip CSP solution for EMI filtering and ESD protection for wireless handset designs implementing a single channel microphone port and a dual channel speaker port in support of stereo audio applications.
