Dual DSP with 4 ch ADC + 4 ch DAC + 4 ch SRC
MP
Description
The AK7735AVQ is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gain amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, 2 stereo sampling rate convertors supporting the sampling frequency up to 192kHz and dual DSPs for Audio / HF process. Each DSP has 3072 step / fs (when fs = 48kHz) parallel processing power. As the AK7735AVQ is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7735AVQ is available in a 48-pin LQFP package.
Key Features
Dual core DSP with Codec and SRC suitable for the automotive devices.
Applications
                                Automotive device applications etc.
