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.
