Cirrus Logic Inc. has introduced the industry’s highest-performance audio system-on-a-chip (SOC), the CS47048, targeting audio amplifier applications. By combining an advanced 32-bit audio DSP, high performance multichannel audio codec and a digital audio receiver/transmitter into a single IC, the CS47048 dramatically reduces overall board space requirements and system cost.
The CS47048 features an advanced, 32-bit single core audio processor with powerful customer programming tools and multibit Delta-Sigma audio converter technology, both of which provide best in class performance. This integration allows audio amplifier designers to greatly simplify designs by reducing the number of ICs required to implement an automotive amplifier by as many as 10, depending on channel count and signal processing requirements. This chip reduction, which includes A/D converters, D/A converters, DSP, memory, and SPDIF I/O, dramatically reduces the board space required and system cost.
“With the CS47048, we’ve packed a high performance audio DSP and audio converters onto the same piece of silicon and supported it with our easy to use DSP Composer programming environment,” said Jason Rhode, President and CEO, Cirrus Logic. “It’s a strong technological achievement, and it allows designers to reduce component count and more easily achieve their system requirements without sacrificing audio quality.”
Cirrus Logic expects to sample the CS47048 to key customers in the December quarter of 2008. The CS47048 is available in a 100-pin LQFP package and is priced at $6.12 in quantities of 10,000. For more information, visit www.cirrus.com.
