IS2008

IS2008/10/13/15 SoC Bluetooth® 4.1 Mono Audio SOC Features System Specification  Compliant with Bluetooth Specification v.4.1 (EDR) in 2.4 GHz ISM band  It supports following profiles : - HFP 1.6 - HSP 1.1 - A2DP 1.2 - AVRCP 1.5 - SPP 1.0 - PBAP 1.0 Baseband Hardware  16MHz main clock input  Built-in internal ROM for program memory  Support to connect to two hosts ( phones, tablets…) with HFP or A2DP profiles simultaneously  Adaptive Frequency Hopping (AFH) avoids occupied RF channels  Fast Connection supported RF Hardware  Fully Bluetooth 4.1 (EDR) system in 2.4 GHz ISM band.  Combined TX/RX RF terminal simplifies external matching and reduces external antenna switches.  Max. +4dBm output power with 20 dB level control from register control.  Built-in T/R switch for Class 2/3 application  To avoid temperature variation, temperature sensor with temperature calibration is utilized into bias current and gain control.  Fully integrated synthesizer has been created. There requires no external VCO, varactor diode, resonator and loop filter.  Crystal oscillation with built-in digital trimming for temperature/process variations. Audio processor  Support 64 kb/s A-Law or -Law PCM format, or CVSD (Continuous Variable Slope Delta Modulation) for SCO channel operation.  Noise suppression  Echo suppression  SBC and optional AAC decoding  Packet loss concealment  Build-in four languages (Chinese/ English/ Spanish/ French) voice prompts and 20 events for each one.
