SMSC announced the availability of the DARR83, a complete digital wireless audio processor with tri-band support and an embedded multi-channel USB 2.0 audio. This IC is appropriate for companies integrating Wi-Fi and Bluetooth into their consumer electronics products. Its support of 2.4, 5.2 and 5.8 GHz frequency bands allows it to seamlessly coexist with Bluetooth and Wi-Fi 802.11 a/b/g/n standards, which minimizes the impact of Wi-Fi on wireless audio as well as the impact of the wireless audio on Wi-Fi throughput. An integrated USB 2.0 PHY and controller enable the DARR83 to act as a USB audio device with the capability to support up to eight mono audio channels for PC-centric wireless audio and video applications. Its multi-point-to-multi-point high definition (HD) wireless audio platform supports 24-bit, 96 kHz sample rate wireless audio transmissions. Bi-directional audio allows the DARR83 to simultaneously transmit and receive audio streams with a latency of 18 ms, complying with Dolby digital audio certification requirements. The DARR83 integrates many automated functions such as seamless RF band switching, RF channel selection, transmitter/receiver association and low power audio snooze mode.
