Description
IS1690S multi-speaker stereo audio chip is a
compact, highly integrated, CMOS single-chip RF and
baseband IC for Bluetooth v3.0 with Enhanced Data
Rate 2.4GHz applications. This chip is fully compliant
with Bluetooth specification and completely backward-
compatible with Bluetooth 2.0 or 1.2 systems.
It incorporates Bluetooth 1M/2M/3Mbps RF, single-
cycle 8bit MCU, TX/RX modem, 5-port memory
controller, task/hopping controller, UART interface,
and ISSC’s own Bluetooth software stack to achieve
the required BT v3.0 with EDR functions.
To provide the superior audio and voice quality, it
also integrates a DSP co-processor, a PLL, and a
CODEC dedicated for voice and audio applications.
For voice, not only basic CVSD encoding and
decoding but also enhanced noise reduction and echo
cancellation are implemented by the built-in DSP to
achieve better quality in both sending and receiving
sides. For the enhanced audio applications, SBC
decoding functions can be also carried out by DSP to
satisfy Bluetooth A2DP requirements.
