Cirrus Logic Teams With International Rectifier to Provide Digital PWM Power Amplifier System Solutions.Business Editors & High-Tech Writers AUSTIN, Texas--(BUSINESS WIRE)--Sept. 18, 2000 Market Leaders in Audio and Power Driver IC's to Offer Customers Complete Solution for PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a Amplifier Systems 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 world's market leader in audio chips, today announced the company has entered into a joint marketing agreement with International Rectifier International Rectifier Corp. (NYSE: IRF) is a manufacturer of power semiconductors (MOSFET, IGBT, diodes and thyristors), located in El Segundo, California, USA. It has a market capitalization of 2.48 billion USD and is listed on the S&P Midcap 400. (NYSE NYSE See: New York Stock Exchange :IRF IRF Interferon Regulatory Factor IRF International Religious Freedom IRF Institut for Rationel Farmakoterapi (German) IRF Inherited Rights Filter (Novell) IRF Inherited Rights Filter ), the power conversion experts, to develop a complete system solution for digital Pulse Width Modulation See PWM. (PWM) power amplifiers. The new digital PWM from Cirrus Logic represents a significant advancement in Crystal(R) audio technology that reduces power requirements for audio amplifiers, dramatically improves sound quality and reduces cost and complexity of design for audio applications. Under the terms of the agreement, Cirrus Logic will work with International Rectifier to incorporate International Rectifier's power driver ICs and MOSFETs into a complete system level solution that includes Cirrus Logic's new digital PWM amplifiers, software and hardware support. The two companies also will co-develop a new power driver IC optimized for PWM technology and will develop additional products to meet customer needs. The agreement will allow Cirrus Logic to offer manufacturers a complete end-to-end solution for designing, building and manufacturing the next generation of amplifiers that are smaller, more power efficient and produce a higher quality of sound than existing technology today. "Working with the recognized leader in power driver ICs and MOSFETs on the next generation of amplifier technology offers a significant advantage for our solution in the marketplace," says Jason Carlson, vice president and general manager of Cirrus Logic's Consumer Products Division. "From power-conscious products that conserve every milliwatt mil·li·watt n. Abbr. mW A unit of power equal to one thousandth (10-3) of a watt. Noun 1. milliwatt - a unit of power equal to one thousandth of a watt of energy all the way up to high-end consumer and non-consumer systems that require multiple killowatts of power, this agreement will allow us to provide our customers with a complete end-to-end solution, including software and hardware support, so they can get their products to market faster." According to David Tam, International Rectifier Power IC Group vice president, "The digital PWM audio amplifier is a promising market area for IR's industry-leading high-voltage power ICs and MOSFETs. The market potential for both companies is huge. Our new working relationship with Cirrus Logic is in line with our corporate-wide philosophy to provide complete, value-added power solutions. The two companies will create reference designs using existing standard products as well as cutting-edge products to be developed in the future."
