CRUS Cirrus Logic Inc

Manufacturers of portable devices such as media players, navigation devices, wireless headsets, voice recorders and gaming products now have access to Cirrus Logic Inc.�s (Nasdaq: CRUS) flagship portable audio codec, the CS42L55. Consuming only 5.1 mW quiescent power in playback mode and featuring a unique bimodal, patent-pending Class H technology, the 24-bit CS42L55 reduces power consumption by nearly 50 percent compared to Class A/B amplification found in portable applications today. This innovation helps to increase battery life operating at standard audio sample rates and delivering power into headphones in real-world audio playback conditions by as much as two additional hours while maintaining high audio quality. The CS42L55 features an ultra small 5x5 mm footprint, and at 0.45 millimeters in height, it is one of the thinnest portable audio codec available today. �No other portable audio codec in production offers the combination of performance, feature integration, battery life and overall small size like the CS42L55,� said Jason Rhode, president and chief executive officer, Cirrus Logic. �This IC is a prime example of why Cirrus Logic has become the new technology innovator in low-power audio products. We continue to take significant market share in portable audio products as customers value the innovation that we provide.� The CS42L55 features automatic, supply-adjusting bimodal Class H headphone driver technology and an innovative charge pump architecture with ground-centered outputs. These technologies have become the innovative foundation for Cirrus� line of portable audio products and allow its codecs to achieve ultra low power consumption and EMI performance well below industry requirements. Based on 24-bit advanced multibit Delta-Sigma technology, the CS42L55 operates from a single 1.8 V or 2.5 V power supply and can deliver 1 VRMS line output from a 1.8 V supply. When driving headphones from the same supply it can deliver 17 milliwatts per channel of high-quality, 96 dB dynamic range audio. The CS42L55 also provides a 2:1 stereo input multiplexer and a USB master clock input and supports sample rates up to 48 kHz. The CS42L55 also features analog volume control that helps to increase performance and reduce the overall noise floor. Further, pseudo differential outputs allow for routing signals while reducing noise coupling in analog signals. Pricing and Availability The CS42L55 is available today in a 36-pin xQFN package, priced at $1.73 in quantities of 10,000. Cirrus Logic Inc.
