描述 Description

The AK7737 is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gainamplifiers, a 24-bit stereo ADC with input selector, 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/HFprocess. The DSP1 and the DSP2 have 6144step/fs (when fs=48kHz) parallel processing power. TheAK7737 is capable of processing sound and voice such as for hands-free function simultaneouslybecause two DSPs are able to work on different but synchronized sampling frequencies. As the AK7737is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects andproprietary high performance hands-free function. The AK7737 is available in a space saving 64-pinHTQFP package.
