AK7738

[AK7738] AK7738 Multi DSP with 5ch ADC + 4ch DAC + 8ch SRC 1. General Description The AK7738 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, a monaural ADC, two 32-bit stereo DACs, 4 stereo sampling rate convertors supporting the sampling frequency up to 192kHz, two DSPs and a Sub DSP for Audio/HF process. Each two DSPs and a Sub DSP has 2560step/fs (when fs=48kHz) parallel processing power. The AK7738 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 AK7738 is a RAM based DSP, it is freely programmable for user requirements, such as acoustic effects and proprietary high performance hands-free function. The AK7738 is available in a 64-pin LQFP package. 2. Features □ DSP1/DSP2: (Memory areas are shared by DSP1 and DSP2) - Word length: 28-bit (Simple floa...
