1. Introduction
This document is manual for BTW200 module. BTW200 module is for sending & receiving audio data
without wire. Transmission methods are FHSS(Frequency Hopping Spread Spectrum) which is used in
bluetooth technology.
BTW200 is composed of two parts. One is Tx module and the other is Rx module. Tx module is works for
master, which receives and compresses audio signal at baseband chip and sending signal without wire.
Rx module is works for slave, which receives signal without wire. The both modules can send and
receive data each other.
This system is for sending and receiving wireless digital data with CD audio quality. The following
characteristics are for satisfying quality.
- Bluetooth RF chip is used for RF function without wire.
- DWM3100 supports audio interface, works for compressing & decompressing and controls audio codec
& RF modem chip.
- Real-time sending and receiving are available.
- It could works independently without S/W control. To loading parameter for operating DWM3100 when
you turning on the power, Booting EEPROM(128 bytes or 256 bytes) is implemented on set. In addition,
I2C mater function is included for accessing EEPROM.
- There is another interface for testing system, additional data interface a nd controlling other system.
- CD audio quality is available.
- Data transmission is possible.
- Can avoid interference with other wireless products.
- Operation clock and master clock are used.
32MHz clock for baseband part and RF
