Description
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. (...
