USB Audio Controllers Invade Mini/Micro Stereo Markets

Optimized for use in mini and micro stereo systems, the UAC 3553B family of USB audio controllers allow the end user to stream digital music files from the PC into the stereo and control the system by using the existing buttons on the stereo via the USB interface. Also, the LCD or the on-screen display on the stereo system can be used to show digital file play lists independently from the PC display. The device works with Musicmatch and Winamp software, which control communications and audio streaming between stereos and PCs. Core functional blocks integrated on UAC 3553B devices include a controller that provides the USB interface and a digital processing unit with a three channel D/A converter. All devices in the family are available in a 44-pin PMQFP. The UAC 3553B is priced at 2.90 each in high volume quantities. MICRONAS, Freiburg, Germany. +49-761-517-2324.
