NEW

Description

The AK7739 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, 4 stereo & 4 monaural sample rate converters (SRCs) supporting the sampling frequency up to 192kHz, a DIT, two DSPs and a Sub DSP for Audio/HF process. The DSP1 and the DSP2 have 6144step/fs (when fs=48kHz) parallel processing power. The AK7739 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 AK7739 is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7739 is available in a space saving 64-pin HTQFP package .
