Wistron NeWeb Corporation Wireless Audio Module AVMD7300RX(SWA8) AmyTu 2011/3/20 VoiceMagic Module Datasheet Point-to-Multipoint AVMD7300 Receiver for Wireless Audio Systems, based on Avneras AV7300 IC General Description Every consumer wants to be free from wires, but system designers could never find a low-
cost, high-quality, easy-to-use wireless audio solution for speakers, microphones, headphones and headsets on the market. Avneras proprietary wireless system changes the game by taking a new approach to wireless audio. The wireless protocol was designed from the ground up and delivers uncompressed stereo audio over the air without interference problems. Avneras wireless modules offer a low-touch, easy-to-integrate wireless audio solution and enable fast time to market by already solving the problem associated with FCC, antenna tuning and board optimization. Avneras AudioMagic technologies provide breakthrough wireless audio functionality with point-to-multipoint transport of uncompressed stereo PCM audio data from a single AVMD7300 or AVMD7300 sender and a total of up four simultaneous AVMD7300 listeners. Modules based upon Avneras next generation AudioMagic incorporate enhanced error concealment, low audio jitter, low latency, reduced power consumption and digital audio interface for the receiver. silicon AV7300 to Applications

AMR corresponds to the maximum value that can be applied without leading to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Range is not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified.
