AK4126
6ch 192kHz / 24-Bit Asynchronous SRC
GENERAL DESCRIPTION
AK4126 is a 6ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 192kHz.
The output sample rate is from 8kHz to 192kHz. By using the AK4126, the system can take very simple
configuration because the AK4126 has an internal PLL and does not need any master clock Then the
AK4126 is suitable for the application interfacing to different sample rates like multi-channel high-end Car
Audio, DVD recorder, etc.
