Cirrus Logic's New Audio D/A Converter Achieves Industry's Highest Dynamic Range: Brings Recording Studio Quality Sound to Consumers.Business Editors & High-Tech Writers Audio Engineering Society Show LOS ANGELES--(BUSINESS WIRE)--Sept. 21, 2000 Cirrus Logic (company) Cirrus Logic - A manufacturer of integrated circuits including the Advanced RISC Machine and display interface processors and cards for use as Windows accelerators (requiring dedicated driver software). http://cirrus.com/. Inc. (Nasdaq:CRUS crus (krus) pl. cru´ra [L.] 1. leg (1). 2. a leglike part. crus ce´rebri ), the worldwide market share leader in audio chips, today introduced the CS43122, a new Crystal(R) digital-to-analog (D/A D/A See: Documents Against Acceptance ) Converter that achieves the highest performance of any audio D/A Converter (Digital/Analog converter) A device that converts digital code into analog signals. The most common applications are for generating sound and video. The D/A converter may be contained on a single chip or can be one circuit within a chip. Contrast with A/D converter. on the market. The CS43122 leverages Cirrus Logic's analog design expertise in an integrated, single-chip D/A Converter with 122dB dynamic range and transparent audio conversion that delivers unprecedented sound quality for high-performance audio systems. Dynamic range is a key audio specification that measures the amount of noise that a converter introduces to a system, which directly impacts sound quality and audio performance. By minimizing the noise level to the lowest in the industry, the CS43122 achieves 122dB dynamic range and provides transparent digital-to-analog conversion for the ultimate listening experience. "We have combined our analog expertise and broad portfolio of intellectual property to once again set the standard for D/A Converter performance with the CS43122," said Jason Carlson, vice president and general manager of Cirrus Logic's Consumer Products Division. "Consumers can look forward to a new level of performance in next generation audio products, as manufacturers can integrate the CS43122 to deliver professional, high-fidelity audio products with unprecedented sound quality." Consumers will now be able to enjoy audio performance once confined to professional settings such as recording studios. The CS43122 preserves the essence of original audio recordings by delivering transparent digital-to-analog conversion. This ability to reproduce the ambience and atmosphere of a live performance is a characteristic that manufacturers strive to deliver in audio systems such as high-end DVD-Audio players (24-bit, 192kHz sample rates), A/V receivers, outboard converters, mixing consoles and effects processors. The CS43122 achieves the highest dynamic range of any audio D/A Converter in the market (122dB) and THD+N THD+N Total Harmonic Distortion + Noise of 0.0007 percent. The new chip is based on Cirrus Logic's patented multi-bit delta sigma modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. architecture, analog filter technology, and second generation dynamic element matching. Combined, these proprietary technologies allow the CS43122 to achieve a flat noise floor that remains constant regardless of input signal characteristics. The CS43122 is an integrated, single-chip solution that allows manufacturers to achieve the highest level of performance so they can provide innovative professional and high-fidelity audio products to consumers. Pricing and Availability The Crystal CS43122 is offered in a 28-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. package and is currently available, priced at $12.20 in OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and quantities. Cirrus Logic Cirrus Logic is a premier supplier of high-performance analog and DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive chip solutions for Internet entertainment electronics. Building on its global market share leadership in audio integrated circuits and its rich mixed-signal patent portfolio, the company targets high-volume audio, storage and communications applications. Cirrus Logic sells its products under the Crystal(R), Maverick(tm) and 3Ci(tm) brands as well as its own name.
