Audio Sub-System (TVP5157 and TVP5158 Only)
The audio sub-system integrates a 4-Ch audio analog-to-digital converter, digital processing, and I2S
encoder. TVP5158 audio sub-system supports 4-Ch mono analog audio input and standard/multiple I2S
output. TVP5158 also supports audio cascade connection up to four devices cascade connected for 16-Ch
audio input.
