Brief Description
The GS9023B is a highly integrated, single chip solution for the multiplexing/demultiplexing of digital audio channels into and out of digital video signals. The GS9023B supports the multiplexing/demultiplexing of 20 or 24-bit synchronous audio data with a 48kHz sample rate. Audio signals with different sample rates may be sample rate converted to 48kHz before and after the GS9023B using audio sample rate converters.

KEY FEATUREs
• single chip embedded audio solution
• operates as an embedded audio multiplexer or demultiplexer
• full support for 48kHz synchronous 20/24 bit audio
• 4 channels of audio per GS9023B
• cascadable architecture supports additional audio channels
• multiplexes and demultiplexes arbitrary ANC data packets
• support for 143, 177, 270, 360 and 540 Mb/s video standards
• full processing of audio parity, channel status and user data
• multiplexes and demultiplexes audio control packets
• EDH generation and insertion when in Multiplex Mode
• 3.3V core with 3.3V or 5V I/O (requires 5V supply)
• complies with SMPTE 272M A, B, and C
