Multi-channel Audio DSP

The KM103S series provides the necessary audio functions on a single chip for applications with multiple audio channels, such as audio mixers, amplifiers, multichannel speakers, conference systems, musical instruments, and car audio.

It has a built-in multi-channel audio interface, high SNR A/D,D/A converter, wideband sampling rate converter, audio DSP that realizes various sound effects, and a general-purpose microcontroller.

Integration contributes to cost reduction and higher audio quality.

Features

-	Analog and digital interfaces that can input and output up to 12 channels of audio
-	A/D converter/D/A converter (2ch x 3 each) SNR: ADC105dB, DAC113dB
-	Sampling rate converter covering 8 KHz to 192 KHz (2ch x 9)
-	Audio DSP EQ, Mixer, Compressor, Surround etc. that realizes various sound effects.
-	We provide evaluation boards, SDKs, and audio design tools for customer development support.
