1. Product Description

The DWPCIe83 USB module is a wireless audio module (30x26.8mm) with a PCI

Express interface based on the SMSC DARR83. This USB module can be used to build

an uncompressed wireless digital audio transceiver operating in the 2.4GHz, 5.2GHz and

5.8GHz bands.

The wireless audio link supports up to four stereo audio streams and comes together with

additional features such as: data encryption, pairing functionality, bi-directional control

data messages, low power audio snooze mode, WLAN detection and Automatic

Frequency Allocation.

The DARR83 chip itself provides the basic functions of Audio Processing and buffering, Data

Link Layer and Physical Layer. The DWPCIe83 USB module integrates all functionality for a

wireless digital audio connection, comprising:

• DARR83 Wireless Audio Processor

• 2.4GHz/ 5.2GHz/ 5.8 GHz RF Transceiver

• Dual antenna connectors

• USB2.0 through a PCI Express Mini Card System Connector

• Built-in SPI interface Flash

2. DWPCIe83 Module Usage Scenarios

2.1. Headset Mode

When the DWPCIe83 Module is configured into the headset mode the DWPCIe83 module is

able to have an audio input and audio output at the same time. The DWPCIe83 module can

stream audio to a DARR-enabled headset and simultaneously receive the voice channel from

this headset.

2.2. Multiple Stream Mode

In the multiple stream mode the DWPCIe83 Module will act as a multi stereo stream device

so that in Windows Vista and Windows 7 it is possible to play multiple audio sources (iTunes

and medial player) to different speakers.

2.3. Surround Mode

When the DWPCIe83 Module is configured in the surround mode it is possible to transfer

5.1/7.1 audio from a movie to wireless surround speakers.

2.4. Customer Specific Applications

An SDK for the DARR83 USB dongle is available at SMSC. For more information on the SDK,

the features and support for application specific developments, please contact SMSC.

2.5. RF measurement

Conducted measurement is through IPEX connectors. For radiated measurements, suitable

external antennas have to be connected to the IPEX connectors.

Laboratory tests have verified coexistence with interference sources collocated. Exact ranges are scenario dependent

(function of latency, output power, audio compression, etc.). A mix of interference sources is allowed. Interference of fixed

frequency devices may result in the loss of one useable RF channel.
