Rev0.0  Page2of91. Product Description The WISP50S module is a wireless audio module (60X21mm)) based on the SMSC DARR83. This module can 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 two 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 WISP50S module integrates all functionality for a wireless digital and analog audio connection, comprising: 2. Features  DARR83 Wireless Audio Processor  2.4GHz/ 5.2GHz/ 5.8 GHz RF Transceiver  Embedded Antennas  Digital audio interfaces (I2S)  Integrated 24 bit stereo Audio DAC + Headphone AMP  Integrated 16 bit Audio ADC + Microphone AMP  Built-in SPI interface Flash  9 pins interface connector for power, audio output, control interface and GPIOs  Regulated 5V supply 3.

The single ended output of the TR switch is connected to the RF LNA input through Diplexer and matching networks. Filtering and amplification is all performed by the radio transceiver. The gain setting is controlled by the BB. The analog IQ outputs are sampled by the BB by its integrated 22Msps dual channel 8bit ADC. This received data is demodulated and fed to the audio processing engine controlling the audio function. 4.4 Transmit mode In transmit mode, the audio engine transforms the audio data into packetized digital IQ signals. These are in turn pulse-shaped before conversion by a 10bits 44Msps DAC to match to the analog IQ inputs of the radio IC. The radio IC has programmable baseband filters to lower the RF spectrum side lobes
Rev0.0  Page4of9and to suppress the DAC image and the DAC spurious. The output power is programmable. A power detector (PD_out) on the radio IC enables close-loop TX power control. The differential RF PA outputs are connected via a baluns and Diplexer to a transmit/receive switch with TX diversity option to the RF connectors. 5. Clock and synthesizer frequencies The main crystal is connected to the Baseband IC crystal oscillator. This in turn buffers this 44MHz and feeds it to the radio IC. In standard configurations, the DARR83 based DWPCIe83 module’s RF section runs at the following frequencies: 2.4GHz Band: The RF oscillator runs at 2 times the programmed RF output frequency.
