3. Operation Description
Samsung wireless audio module is the 2.4GHz band RF Module that provide users of a wireless audio
system to connect to TV. 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 (16MHz) 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.
4. Application for Wireless audio module
The application for the Tx and Rx modules is for the wireless link between a Samsung Sound Bar and a sub-
woofer.

6. Pairing Algorithm
The system has both “auto-pairing” and manual pairing capabilities. Auto-pairing can be used at the factory for
testing purposes but all units are shipped from the factory with “auto-pairing” enabled. This means the user can
unpack the sound bar and sub woofer and they will link immediately without user interaction. It does present an
issue if there is another unit close by as erroneous operation can result if a sound bar connects to the wrong sub
woofer. Auto-pairing persists for up to 30 seconds after units are powered up.
There is also the capability to manually pair the sub woofer to the sound bar. This is accomplished by turning on
the sound bar and setting it to pair mode via the IR remote (push the mute button for > 5 seconds). The sub
woofer can be put into manual pairing mode by pushing the button on the back panel for > 5 seconds when it is
not in a link. If the sub woofer is already linked it is not possible to enter pairing mode.
The Tx command set with the sound bar module includes a method to return the system back to auto pairing
mode but this is not a user feature – only for factory use.
7. Installation
This module must be installed in a device and not allow the user to replace nor modify it. And the location is ad

Notice
FCC Statement
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
This device and its antenna(s) must not be co-located or operation in conjunction with any other
antenna or transmitter.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC
compliance requirement of the end product, which integrates this module.
20cm minimum distance has to be able to be maintained between the antenna and the users for
the host this module is integrated into. Under such configuration, the FCC radiation exposure limits
set forth for a population/uncontrolled environment can be satisfied.
