This Bluetooth Dual Mode v5.2 Digital Baseband IP is the design data base of a production Bluetooth Dual Mode SoC shipped in smart phones. The Baseband IP is compliant with Bluetooth Classic and Low Energy standards including BT 2.1 + BT 3.0 + EDR + BT 5.2 and BLE. Firmware source code is supplied to enable interface into protocol Stack SW at the HCI layer through UART and I2S.
The A2DP offloading can also be performed with audio data transferred from Host over PCM or I2C of Stereo Audio Data samples (44.1 or 48 Khz) to/from the IP. Data can be transferred in burst mode over the PCM / I2S interface in order to achieve significant host power consumption improvements during A2DP playback. The IP embeds support of modified SBC encoding and decoding for Wideband speech. The Whole processing is performed internally and does not require dedicated processing from Host side.
An optional DSP (CoolFlux) is integrated into the audio path to provide audio processing capabilities from Wide-Band Audio Codec implementation to MP3 and noise cancellation.
