AK4121

Asynchronous Sample Rate Converter

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.
