Overview
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 codec  94dB SNR DAC playback  85 dB SNR ADC.
