Multimedia Bluetooth 3.0 APTX Module For Stereo Speaker , CSR 8645 ROM Chip
Product Description
This is a Bluetooth Class2 (max 4dBm) module. It is based on CSR 8645 ROM version chip
set which supports Bluetooth V3.0 standard and CSR APTX audio streaming. The APTX feature
provide high quality audio streaming compared to traditional SBC coding. Its latency time is as
low as 75ms which is sufficient for most of the multimedia applications. The Embedded Kalimba
DSP Co-Processor also support the advanced features such as echo cancellation, noise reduction ,
and stereo audio (A2DP profile) communications. Advanced user interface design allows multipoint
HFP or A2DP connections and secure simple pairing. The integrated stereo DAC provide high quality
audio performance with SNR up to 95dB. Support digital audio bus such as PCM, I2S or SPDIF. And
the on chip Switched-Mode Regulator and Li-ion battery charger eliminate the needs of external
components and costs. The true single chip solution to audio applications. Internal ROM, serial flash
and EEPROM enable the flexibilities of the module to meet various kinds of applications.
