2ch Digital Sample Rate Converter (SRC). The input sample rate ranges from 8kHz to 768kHz. The output sampling rate is 8kHz to 768kHz. The AK4137EQ has an internal oscillator. Therefore, it does not require any external master clock and simplifies system configuration. The AK4137EQ is suitable for applications with different sample rates, such as high-end audio systems and USB-DACs. It is capable of playing various audio formats with PCM-DSD data conversion.

● PCM / DSD conversion function

The AK4137EQ supports conversion from 2.8 / 5.6 / 11.2MHz DSD to PCM format and vice versa.

●Maximum sampling frequency, bit rate: PCM768kHz / 32 bits, DSD256 (11.2MHz)

●DR: 186dB

●THD + N: -150dB

●Sound color digital filter: 4 types

●Application

It is very suitable for application audio quality such as network audio focusing, SACD player, high-end audio system, car infotainment system, etc.
