Introduction

The AK4136 is a 2ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 384kHz. The output sample rate is from 8kHz to 384kHz. The AK4136 has an internal Oscillator. Therefore it does not need any external master clocks and simplifies system configuration. The AK4136 is suitable for a high-resolution audio application interfacing to different sample rates such as Network Audios, USB DACs and Car Audios.
