CS4920A Datasheet | Crystal Semiconductor

Features - General Purpose Digital Signal Processor Optimized for Audio 24 Bit Fixed Point 48 Bit Accumulator 12.3 MIPS @ 48 k Hz Sample Rate - On-Chip Functional Blocks Include: -CD Quality D/A Converters -Programmable PLL Clock Multiplier -AES/EBU - S/PDIF patible Digital Audio Transmitter -Audio Serial Input Port -Serial Control Port - Applications Include: -Audio Depression -MPEG 1 and 2 Layers I, II - Standard 44 pin PLCC Package General Description The CS4920A is a plete 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 patible 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 pressed digital audio. Serial audio data broadcast on networks such as cable TV, direct broadcast satellite TV, or the telephone system can be depressed 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 I, II is available. A plete set of software development tools are available. These include an assembler, simulator, and debugger.
