ASAHI KASEI

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 AK4124, 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 the AK4124 is suitable for the application interfacing to different sample rates like

high-end Car Audio, DVD recorder, etc.
