NKR-SWA52Wireless Audio Module

CONFIDENTIAL | PROVIDED UNDER NDA General Description The SWA52 module is a member of a family of products representing a new level of system integration offering customers fast time to market with a point-to-point mono, or stereo, wireless connection. These modules are optimized for low-cost, high-quality and ease- of-use. The module incorporates Avnera’s proprietary 5GHz wireless audio protocol, designed from the ground up specifically for audio. It features low fixed latency, uncompressed CD quality mono or stereo audio, superior interference immunity, and inherent coexistence with WiFi. Extended range is enabled on SWA52 with an external RF power amplifier (PA), increasing typical transmit power to as much as 12dBm typical. The SWA52 module integrates all features necessary to complete a wireless stereo or mono link, including AV5100 Wireless Audio Chip, printed diversity antennas, PA, shield can , flash memory, interface connector and all passive components. Just provide power and an I2S interface and you are ready to create a wireless audio link. The module measures 35 x 35 x 3.5 mm and is provided with a 24 pin FPC connector. The module is certified to FCC and CE standards.
