Description

The AK7719B is a highly integrated digital signal processor (DSP) with five digital interface ports. The built-in asynchronous sample rate converter (SRC) enables flexible connectivity in various system configurations. 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. The RAM-based DSP can be programmed for user requirements. The AK7719B is housed in a 30-pin CSP package. It is a very low power device, suitable for mobile applications.
