[AK4141] AK4141 NICAM/A2/EIA-J Digital Stereo Decoder GENERAL DESCRIPTION The AK4141 is a NICAM/A2/EIA-J stereo decoder, which is optimized for Digital TV application. The AK4141 achieves no alignment, few external components and high audio performance by digital stereo decoding architecture. The AK4141 integrates a stereo sample rate converter SRC for asynchronous digital audio sources such as digital tuners, digital switches and sound processing functions like 5-band equalizers. The AK4141 supports major audio data formats MSB/LSB justified, I2S and TDM to interface with DSP, ADC, DAC. Therefore, the AK4141 is suitable for the AV systems such as Digital TV and DVR.
