AK4128A

8ch 216kHz / 24-Bit Asynchronous SRC

GENERAL DESCRIPTION

The AK4128A is an 8ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to

216kHz. The output sample rate is from 8kHz to 216kHz. The AK4128A has an internal Oscillator and

does not need any external master clocks. It contributes simplifying a system configuration. The AK4128A

supports master mode and TDM data interface, enabling simultaneous input of asynchronous stereo

data. The AK4128A is suitable for the application interfacing to different sample rates such as

multi-channel high-end Car Audio Systems and DVD recorders.
