Sample Rate Converter
AK4127
192kHz Asynchronous Sample Rate Converter with PLL
The AK4127 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. The AK4127 has an internal PLL and does not need any master clock at slave mode. The AK4127 also supports cascading connection of up to four devices (8channels) in a daisy chain configuration at TDM mode. In this mode, the system can take very simple configuration because the TDM mode can convert the data line with the different sample rates in high-end system such as Studio equipments, Car Audio and DVD recorder into one data line.
