LG-KS.WT0601Wireless Digital Audio TX Module User Manual
LG-KS.WT06011. IntroductionThe series of modules from LG are designed for the wireless audio transmission and reception with providing a high-end quality of DVD receiving speaker system audio. The transmission technique used in the module is DSSS (Direct Sequence Spread Spectrum) that is also adopted in the IEEE 802.11b specification, and the datarate can be up to 2Mbps with constant and continuous transmission.The antenna has the 1dBi (Peak) gain.The Oscillator frequency is operated as 44MHz and provide RF channel scanning function, then the transmittercan choose a clear channel and coexist with the WLAN system in the same environment.The channel use the 1~12Ch and also automatically scan the best optimized channel without noise. When inputting the initial power, this Channel will be shifted to the best optimized condition to receive and transmit the high qualified sound between the transmitting module and receiving module. In this user manual, it will describe specifications and operating steps for these wireless system board..
LG-KS.WT06011. System DescriptionsThe LG-KS.WT0601 module high-end digital wireless audio solution is a concept combination with system module, and main board.The system module is a complete design, which includes all parts of RFIC, IA8 IC, optional audio I/O chip and connector in the single board. (1) Clock generation1 . Use a 44MHz clock signal as reference clock of internal programmable PLL circuit to generate the audio system clock to the external ADC. Audio clock: SYS_CLK: 12.288MHz (512Fs), BCK: 3.072MHz, LRCK: 48KHz.2. LG-KS.WT0601 have the internal PLL is configured as output frequency being 24/25 of reference clock (44MHz). Then, the output clock frequency is 44MHz*24/25=42.24MHz. This clock is used as Base Band chipIA8’s operating clock signal for audio sampling clock being 48KHz
