Embedded Audio Codec

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. To simplify system design, the GS9023 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 Gennums GS9032 the GS9023 provides a low power, highly integrated two chip solution for SDI transmit applications. In combination with Gennums 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 By Unkown
