[AK4121A] www.DataSheet4U.com 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. FEATURES † Stereo asynchronous sample rate converter † Input sample rate range (FSI): 8kHz to 96kHz † Output sample rate (FSO): 32kHz/44.1kHz/48kHz/96kHz † Input to output Sample rate ratio: FSO/FSI = 0.
