AK4121A

Asynchronous Sample Rate Converter

GENERAL DESCRIPTION

The AK4121A 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. Since the internal PLL

eliminates the need for a master clock in slave mode, the AK4121 simplifies the system design.

Therefore, the AK4121A is suitable for applications requiring multiple sample rates, such as Car Audio,

DVD recorders, and digital audio recording.
