Combining its latest Crystal audio technologies, the company has introduced a three-chip home-theater audio solution to deliver the functionality currently performed by as many as eight devices. The chipset includes an audio DSP, audio codec, and an S/PDIF.
Manufactured on 0.25-µm standard CMOS, the fully programmable, 24-bit CS49326 audio DSP contains enough memory to store code for Dolby Digital AC-3 and digital theater sound, eliminating the need for external memory. Reducing design complexity, the CS4228 audio codec has been optimized to interface directly with the DSP, eliminating the need for a buffer IC. The codec features a 24-bit resolution and a 103-dB dynamic range.
The CS8415A is claimed to be the industry's first digital, 96-kHz S/PDIF receiver to integrate a 7:1 input multiplexer. The CS49326 is priced at $16.50, the CS4228 is $8.60, and the CS8415A costs $3 each/10,000.
