AK4140
Digital BTSC Decoder
GENERAL DESCRIPTION
The AK4140 is a BTSC decoder, which is optimized for Digital STB/TV application. The AK4140 achieves
high audio performance using original demodulation techniques for 4.5MHz inter-carrier sound, and the
digital BTSC decoding architecture using digital dbx-TV® technology licensed from THAT Corporation
requires no alignment of external parts. The AK4140 supports major audio data formats (MSB justified,
I2S, TDM) to interface with usual DSP. Therefore, the AK4140 is suitable for the systems such as Digital
STB/TV, AV recorder etc.
The dbx-TV® brand identifies a range of technology solutions for digital TV-audio decoding developed and
licensed by THAT Corporation. The dbx-TV provides high performance solutions with high quality sound.
