摘要
本文给出基于Kinetis MK60N512微控制器和16位/24位音频数模转换器MAX5556的立体声音频接口设计。MK60N512由I2S总线向MAX5556传输音频数据,输出音频信号经有源滤波器进行滤波,保证音频质量的同时提高其带负载能力。由MK60N512内部高性能可编程的增强型DMA向I2S模块传送音频数据,减轻微控制器内核的负担。
The design of stereo audio interface based on microcontroller Kinetis MK60N512 and 16 bit/24 bit audio DAC MAX5566 is given. MK60N512 transfers audio data to MAX5556 through I^2S bus, and output audio signals are filtered by active filters. The design ensures the quality of audio and at the same time, it improves its load capacity. Enhanced DMA of MK60N512 internal performance programmable sends audio signal to I^2 S, and it reduces the burden of the CPU core.
