Description
IS1690S SoC
Bluetooth® 3.0 Multi-Speaker Stereo Audio SOC
Features
System Specification
Compliant with Bluetooth Specification v.3.0 + EDR in 2.4 GHz ISM band
It supports following profiles : - Hands Free 1.5 - Headset 1.0 - A2DP 1.0 - AVRCP 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 3.0 + 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 A-Law or -Law PCM format, or CVSD
(Continuous Variable Slope Delta Modulation) for SCO channel operation. Noise suppression Echo suppression SBC decoding Packet loss concealment Build-in one languages (English) voice prompts and 20 events for each one Support SCMS-T
Audio Codec
16 bit DAC and 16 bit ADC...
