©2008-2011 Gigawit Electronics Ltd. Version 1.01 Page 1 of 14 GWK5NO_SW Datasheet GWK5NO_SW 2.4GHz Wireless Subwoofer Module 1. General Description GWK5NO_SW is the optimized module dedicated for the wireless subwoofer application, it balance well between the cost and performance by utilizing the fact of subwoofer limited frequency response bandwidth. The narrow bandwidth enables GWK5NO_SW to transmit enough redundant data to combat with the 2.4GHz interference thus maintain the good co-existence performance in the 2.4GHz ISM band. Inheriting from its GWK5 family, GWK5NO_SW features both good wireless performance and audio performance. GWK5NO_SW has good RF co-existence and robust link quality, can combat the most interference from the crowded 2.4G ISM band. GWK5NO_SW uses non-compression PCM signal and 24bit high precision thus delivering very low THD audio. By adopting advance forward error correction and error concealment algorithm, GWK5NO_SW can reach <15ms latency, this makes it ideal for the Video synchronization, Home Theater applications. GWK5NO_SW is ideal for the subwoofer application not only by its competitive cost, but also by its flexibility for customized functions. The SW crossover frequency can be adjusted easily by the digital filter, and the general purpose I2C can be used to control customer peripheral unit to eliminate an extra microcontroller. 2.

I2S Digital Audio Interface GWK5NO_SW supports 3 digital audio interface modes: Left justify mode, I2S mode and Right justify mode. Figure [1]. Left Justify Mode Figure [2]. Default I2S Mode Figure [3]. Right Justify Mode ©2008-2011 Gigawit Electronics Ltd. Version 1.01 Page 6 of 14 GWK5NO_SW Datasheet 7. I2C Control Interface GWK5A3T/R features a standard I2C Control interface. The I2C can work as a master or a slave, It can be used to control the peripheral devices or be controlled by the external MCU / DSP. GWK5A3T/R features a two way wireless logical data channel; The I2C can also be used to exchange the control information between the TX and RX side. I2C Address is 0x0e, it is configurable by firmware.
