AK4129

6ch 216kHz / 24-Bit Asynchronous SRC

GENERAL DESCRIPTION

The AK4129 is an 6ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to

216kHz. The output sample rate is from 8kHz to 216kHz. The AK4129 has an internal Oscillator and does

not need any external master clocks. It contributes simplifying a system configuration. The AK4129

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

data. The AK4129 is suitable for the application interfacing to different sample rates such as multi-channel

high-end Car Audio Systems and DVD recorders.
