Avnera Corporation Samsung Module Manual Samsung Module PRD AVNERA CONFIDENTIAL page 3 of 10 1. Introduction This features is a highly integrated, single-chip, wireless audio solution. This integrates the following: a complete 2.4 GHz RF transceiver, the VMI™ wireless communication system PHY & MAC, advanced power management, audio DSP, I2S interfaces and a full complement of programmable digital interfaces to support a wide range of end-product user communication requirements. 2. Hardware Architecture: 2.1 Main Chipset Information Item Vendor Part Number BBIC + RFIC AVNERA AV6200 2.2 Circuit Block Diagram 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.

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.

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.

Avnera Corporation Samsung Module Manual Samsung Module PRD AVNERA CONFIDENTIAL page 8 of 10 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. Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment.
