Sample Rate Converter
AK4129
216kHz 6ch Asynchronous Sample Rate Converter with Internal Oscillator
The AK4129 is an 6ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 216kHz. The output sample rate is from 8kHz to 216kHz. The AK4129 has an internal Oscillator and does not need any external master clocks. It contributes simplifying a system configuration. The AK4129 supports master mode and TDM data interface, enabling simultaneous input of asynchronous stereo data. The AK4129 is suitable for the application interfacing to different sample rates such as multi-channel high-end Car Audio Systems and DVD recorders.
