AK4136
384kHz 32bit SRC
1. General Description
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. Therefor it
does not need any external master clocks and simplifies a system configuration. The AK4136 is suitable for
the application interfacing to different sample rates such as Automotive Audio Systems.
