AK4145
Digital BTSC Stereo Encoder
GENERAL DESCRIPTION
The AK4145 is a BTSC Encoder with D/A Converter, which is optimized for Digital AV application. The
AK4145 achieves high audio performance using the digital BTSC encoding architecture requires no
alignment of external parts. The AK4145 supports major audio data formats (MSB justified, I2S, TDM) to
interface with usual DSP. Therefore, the AK4145 is suitable for the systems such as Digital STB/TV,
digital recorder.
