Cirrus Logic Launches Industry's Lowest Cost, Smallest D/A Converter Providing CD Quality Sound.LAS VEGAS--(BUSINESS WIRE)--April 6, 1998-- New Crystal Mixed-Signal Chip Enables Low Cost DVD DVD: see digital versatile disc. DVD in full digital video disc or digital versatile disc Type of optical disc. The DVD represents the second generation of compact-disc (CD) technology. , Set-Top Box The cable TV box that sits on "top" of the TV "set," although it is often located several feet away in an equipment rack. The set-top box descrambles the premium channels and provides a tuner for the higher cable numbers that very old TVs did not support. , Portable CD, PC Audio Products and Car Audio Systems The Crystal Semiconductor Products Division of 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 NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CRUS crus (krus) pl. cru´ra [L.] 1. leg (1). 2. a leglike part. crus ce´rebri ) continues its advance into the consumer audio market with the introduction of the new CS4334, the industry's smallest, most cost-effective 24-bit 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. . The new Crystal(tm) mixed-signal chip supports sample rates up to 96kHz for superior sound quality and compliance with emerging DVD specifications. Manufacturers using the CS4334 in applications such as set-top boxes, PC audio, automotive audio and DVD systems, as well as MiniDisc A compact digital audio disc from Sony that comes in read-only and rewritable versions. Introduced in late 1993, the MiniDisc has been most popular in Japan. The read-only 2.5" disc stores 140MB compared to 650MB on a CD, but holds the same 74 minutes worth of music due to Sony's Adaptive and portable CD players, can now take advantage of a more integrated solution that enables the trend of digital audio system quality at an analog price. Today's announcement underscores Cirrus Logic's position as the only complete audio solution provider in the world that delivers audio A/D converters, audio D/A converters, audio codecs, digital audio interface chips and audio quality DSPs, all with superior sound quality. The company's newest audio addition is delivered in an 8-pin small outline IC package (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. ) making the CS4334 the industry's smallest delta-sigma audio D/A converter. "The CS4334 continues Cirrus Logic's drive into the worldwide consumer electronics market," said Eric Broockman, vice president and general manager of Cirrus Logic's Crystal Division. "This product brings Crystal's brand reputation for high performance mixed-signal audio products into the emerging DVD market as well as high volume, price conscience markets such as cable and satellite set-top boxes, laptop computers, portable audio and car audio systems." The competitive price of the CS4334 does not mean a sacrifice in quality or functionality. The CS4334 family supports multiple digital interface formats from 16-bits to 24-bits and provides 96 dB dynamic range, -88 dB THD+N THD+N Total Harmonic Distortion + Noise and 96kHz sample rates. Also, unlike many similar D/A converters, the CS4334 offers an on-chip voltage reference A voltage reference is an electronic device (circuit or component) that produces a fixed (constant) voltage irrespective of the loading on the device, power supply variation and temperature. which gives the CS4334 excellent PSRR PSRR Power Supply Rejection Ratio PSRR Product and Support Requirements Request (Sprint) PSRR Preliminary System Requirements Review PSRR Primary Shadow RTO.k Replication PSRR Power Supply Ripple Rejection over the entire audio bandwidth. Additionally, the part is designed to require few external components, further reducing design costs. This is accomplished in part by the implementation of a power transient control circuit that eliminates the need for external mute circuitry which is required by competing DACs to eliminate clicks and pops when the chips power up and power down. Pricing and Availability The CS4334 is currently sampling with volume production available in June 1998. This new device is priced at $1.95 each in 1K quantities.
