General Description

The CS4920A is a complete audio subsystem on a

chip. This device contains a general purpose DSP, a

CD quality stereo Digital-to-Analog Converter, a programmable PLL clock multiplier, an AES-EBU - S/PDIF

compatible digital audio transmitter, an audio serial input port, and a serial control port. The CS4920A is

based on a programmable DSP core and is intended

to support a wide variety of digital signal processing

applications which include decoding compressed digital

audio. Serial audio data broadcast on networks such

as cable TV, direct broadcast satellite TV, or the telephone system can be decompressed and converted to

standard analog or digital signals.

Both industry standard and proprietary DSP algorithms

can be supported. Software which performs industry

standard MPEG 1 and 2 layers 1, Il is available. A

complete set of software development tools are available. These include an assembler, simulator, and

debugger.
