AK4124

ASAHI KASEI [AK4124] AK4124 192kHz / 24Bit High Performance Asynchronous SRC GENERAL 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 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. FEATURES 1.
