Zarlink Semiconductor, Inc. introduces a range of tools that simplify the design of hands-free communication systems including car kits, speakerphones and home automation systems. These design tools include a full evaluation board, mini-evaluation board and a plug-and-test diagnostic kit. The hands-free voice processing evaluation board provides interfaces to connect to PSTN line, cellphone, PC audio port, handset and speaker drivers. The evaluation board is controlled by a GUI (graphic user interface). Accompanying software can be directly interfaced to the customer’s own platform. The mini-evaluation board is smaller than a business card, and it fits directly into most plastic enclosures. The ZLE38000 plug-and-test diagnostic tool kit and software measure key performance parameters including echo profile, frequency response, signal level, and total harmonic distortion.
