AK4137

[AK4137] = Preliminary = AK4137 32bit SRC with PCM/DSD conversion 1. General Description The AK4137 is a 2ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 768kHz. The output sample rate is from 8kHz to 768kHz. The AK4137 has an internal Oscillator. Therefor it does not need any external master clocks and simplifies a system configuration. The AK4137 is suitable for the application interfacing to different sample rates such as high-end Audio Systems and USB-DACs. It is capable of play backing various audio formats with PCM-DSD data conversion function. 2.
