GENERAL DESCRIPTION
The input sample rate ranges from 8kHz to 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. FEATURES
