BRIEF DESCRIPTION
The GS9023A is a highly integrated, single chip solution for
the multiplexing/demultiplexing of digital audio channels
into and out of digital video signals. The GS9023A 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 GS9023A
using audio sample rate converters.
Each GS9023A supports all the processing required to
handle the multiplexing/demultiplexing of four digital audio
channels. To simplify system design, the GS9023A
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 GS9023A supports video standards with rates from
143Mb/s to 540Mb/s. When in Multiplex Mode, the
GS9023A supports the generation and insertion of EDH
information according to SMPTE RP165. In combination with
Gennum’s GS9032, the GS9023A provides a low power,
highly integrated two chip solution for SDI transmit
applications. In combination with Gennum’s GS7005, the
GS9023A provides a low power, highly integrated two chip
solution for SDI receive applications.
The GS9023A requires a 3.3V power supply for internal
core logic and a 3.3V or 5V power supply for device I/O.
