DESCRIPTION
The GS9023 is a highly integrated, single chip solution for
the multiplexing/demultiplexing of digital audio channels
into and out of digital video signals. The GS9023 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 GS9023 using audio sample
rate converters.
Each GS9023 supports all the processing required to
handle the multiplexing/demultiplexing of four digital audio
channels.
seamlessly integrates with common AES/EBU digital audio
receivers and transmitters. The cascadable architecture
allows for the multiplexing/demultiplexing of additional
audio channels with no external glue logic.
The GS9023 supports video standards with rates from
143Mb/s to 540Mb/s. When in Multiplex Mode, the GS9023
supports the generation and insertion of EDH information
according to SMPTE RP165. In combination with Gennum’s
GS9032, the GS9023 provides a low power, highly
integrated two chip solution for SDI transmit applications. In
combination with Gennum’s GS7005, the GS9023 provides
a low power, highly integrated two chip solution for SDI
receive applications.
The GS9023 requires a 3.3V power supply for internal core
logic and a 3.3V or 5V power supply for device I/O.
