AK4124
192kHz / 24Bit High Performance Asynchronous SRC
GENERAL DESCRIPTION
AK4124 is a stereo digital sample rate converter (SRC). The input sample rate ranges from 8kHz to
216kHz. The output sample rate is from 8kHz to 216kHz. By using the AK4124, the system can take very
simple configuration because the AK4124 has an internal PLL and does not need any master clock at
slave mode. Then the AK4124 is suitable for the application interfacing to different sample rates like
high-end Car Audio, DVD recorder, etc.
FEATURES
1. SRC
• Asynchronous Sample Rate Converter

• THD+N : −130dB
• Dynamic Range : 140dB (A-weighted)
• I/F format : MSB justified, LSB justified and I2S compatible
• PLL for Internal Operation Clock
• Clock for Master mode : 128/192/256/384/512/768fsi, 128/192/256/384/512/768fso
