资料介绍

AK7738音频/语音数字信号处理器实现除了音频处理的高性能免提语音处理。环绕声处理和高性能的噪声和回声取消可以同时执行的多核DSP(数字信号处理器)。该器件集成了两个立体声ADC(模数转换器),一个单声道立体声ADC,两个DAC(D/A转换器)和两个SRC的异步采样率转换器。采用先进的32位DAC的模拟输出,实现高质量的高分辨率音源播放。AK7738适用于汽车音响、显示器音响,汽车导航系统和车载免提系统。


The AK7738 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, a monaural ADC, two 32-bit stereo DACs, 4 stereo sampling rate convertors supporting the sampling frequency up to 192kHz, two DSPs and a Sub DSP for Audio/HF process. Each two DSPs and a Sub DSP has 2560step/fs (when fs=48kHz) parallel processing power. The AK7738 is capable of processing sound and voice such as for hands-free function simultaneously because two DSPs are able to work on different but synchronized sampling frequencies. As the AK7738 is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7738 is available in a 64-pin LQFP package.
