AK7719 Overview
The AK7719 is a highly integrated digital signal processor (DSP) with four digital interface ports. AKM’s DSP core is optimized for both narrowband and wideband voice processing, as well as full bandwidth digital audio processing. An integrated clock generator for the DSP master clock eliminates the need for external clocks.
