AKM Semiconductor Inc. AK4128AEQ

Description
The AK4128A is an 8channel digital sample rate converter (SRC).
Input sample rate range: 8kHz to 216kHz.
Output sample rate range: 8kHz to 216kHz.
Internal oscillator eliminates the need for external master clocks.
Supports master mode and TDM data interface for simultaneous input of asynchronous stereo data.
Suitable for applications interfacing to different sample rates, such as multichannel highend car audio systems and DVD recorders.
