... Audio/Hands Free DSP with Stereo CODEC The AK7753 is a digital signal processor with an integrated stereo CODEC. The digital signal processor (DSP) can execute a high-quality hands-free algorithm, using only internal memory. Fine tuning is available for improving voice quality of the hands-free function in actual user environments. The AK7753 includes delay RAM, an integrated PLL, four digital audio input and eight digital audio output ports ...
