AK4127
192kHz / 24Bit High Performance Asynchronous SRC
GENERAL DESCRIPTION
The AK4127 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. 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.
