AK4127 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4127 is a stereo digital sample rate converter (SRC). The input sample rate ranges from 8k Hz to 216k Hz. The output sample rate is from 8k Hz to 216k Hz. The system can take very simple configuration because the AK4127 has an internal PLL and does not need any master clock at slave mode. The AK4127 is suitable for the application interfacing to different sample rates such as high-end Car Audio and DVD recorder. FEATURES 1.
