LG-KS.WT0601
Wireless Digital Audio TX Module User Manual
LG-KS.WT0601
1. Introduction
The 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 data
rate 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 transmitter
can 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..

1. System Descriptions
The 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 c
hip and connector in the single board.
(1) Clock generation
1 . Use a 44MHz clock signal as reference clock of internal programmable PLL circuit to generate the audio sys
tem clock to the external ADC. Audio clock: SYS_CLK: 12.288MHz (512Fs), BCK: 3.072MHz, LRCK: 48
KHz
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 chip
IA8’s operating clock signal for audio sampling clock being 48KHz

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.
Warning: Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
NOTE: 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 or more 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.
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 2
0 cm from all persons and must not be colocated or operating in conjunction with any antenna or tran
smitter other than those contained in this device.
Operation is subject to the following two conditions: (1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operatio
n of the device.
