Operational Description Samsung wireless audio module is the 5GHz dual band RF Module that provide users of a wireless audio system to connect to TV. This uses 5GHz RF 2 channels. (5.2GHz band (5180, 5210, 5240 MHz), 5.8GHz band (5736, 5762, 5814MHz)) This enables a wide range of digital wireless audio applications. This wireless audio technology has been known for its extreme wireless fidelity and audio quality. This module further extends this offering a high level of integration resulting in a very low-cost complete wireless system solution, without any sacrifice to the main technology drivers: Audio Quality and Wireless Fidelity. - Time base of the RF frequency For Zero IF and RF frequency, a crystal (44MHz) is a clock reference. - Synthesizer Synthesizer inside transceiver internal voltage controlled oscillator (VCO) provides the desired LO Signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. - Transmission In transmit mode, the audio engine controlled I2S, transforms the audio data into packetized digital IQ signals. These are in turn pulse-shaped before conversion by a 10 bits 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 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 balun and low pass filter to a transmit/receive switch with TX diversity option to the antenna outputs. - Receiver In receive mode, antenna diversity is supported. The single ended output of the TR switch is connected to the RF LNA input through a matching network. 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 22 Msps dual channel 8bit ADC. This received data is demodulated and fed to the audio processing engine controlling the I2S connections. - Power Control Level The integrated PA for this device can transmit at a maximum power of +4dBm for class 2 operation. - Transmit/Receive Switch DUT has Transmit/Receive Switch. End user can’t select any power setting. 3. Application for Wireless audio module With bidirectional audio stream transmission feature and stream broadcast/Unicast mode supported, this module supports unidirectional Audio Ack, NAck, Bidirectional Audio NAck, Headset Ack applications.
