CRY580 A²B Audio Codec
The CRY580 A²B Audio Codec is a key component in automotive audio systems. It converts A²B-transmitted digital audio and control signals into formats that amplifiers, speakers, and other devices can use for playback and processing.
It transmits bidirectional PCM data, clock signals and sync signals over a single differential pair, supporting multi-channel I²S/TDM. Stable communication is maintained up to 15meters (49 feet) node distance, with 1 to 1 or 1 to many connections enabling shared time-division channels.
