NAB CONVENTION, LAS VEGAS -- April 6, 1998 –The Crystal Semiconductor Products Division of Cirrus Logic Inc. (NASDAQ:CRUS)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. The new CrystalTM 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 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) 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 and 96kHz sample rates. Also, unlike many similar D/A converters, the CS4334 offers an on-chip voltage reference which gives the CS4334 excellent PSRR 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.
