GENERAL DESCRIPTION
AK4121 is a stereo asynchronous sample rate converter. The input sample rate ranges from 8kHz to
96kHz. The output sample rate is 32kHz, 44.1kHz, 48kHz or 96kHz. Using the AK4121 simplifies
system design, since the AK4121’s internal PLL eliminates the need for a master clock in slave mode.
Then the AK4121 is suitable for applications requiring multiple sample rates, such as Car Audio, DVD
recorders, and digital audio recording.
