Description

AK4124 is a stereo digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 216kHz. The output sample rate is from 8kHz to 216kHz. By using the product, the system can take very simple configuration because the AK4124 has an internal PLL and does not need any master clock at slave mode. Then it is suitable for the application interfacing to different sample rates like high-end Car Audio, DVD recorder, etc.
