Burr-Brown Announces Industry's First CD-Quality Audio CODEC.TUCSON, Ariz.--(BUSINESS WIRE)--June 6, 1997--Burr-Brown announces the PCM (1) See phase change memory. (2) (Plug Compatible Manufacturer) An organization that makes a computer or electronic device that is compatible with an existing machine. 3000/3001, an 18-bit, single chip, serial interface, stereo audio CODEC (analog-to-digital and digital-to-analog converter) with single-ended analog voltage input and output -- the industry's first CD-quality CODEC. The PCM3000/3001's low cost, small package, ease-of-use, and high functionality make it ideal for a wide variety of cost-sensitive applications including sampling keyboards, surround-sound processors, digital mixers, Mini-Disc recorders, hard-disk recorders, karaoke systems, DSP-based car stereo, video conferencing, and voice recognition systems for car navigation. The PCM3000/3001 has garnered significant early design win momentum in high quality digital musical instrumentation applications, further establishing Burr-Brown's leading position in the consumer digital audio market. According to Euromonitor's World Market for Consumer Electronics Report, the in-home, portable, and in-car audio markets exceeded $45 billion in 1996. Burr-Brown's digital audio products address all three of these growing consumer segments and assist manufacturers in achieving CD-quality sound or better. In addition, an increasing number of consumer and business applications, such as set-top boxes and video conferencing, are demanding CD-quality audio in their products. "Our PCM3000/3001 has combined high performance CD-quality features at a low cost," said Mike Pawlik, vice president of marketing at Burr-Brown Corp. "We are scoring major design wins where functionality, size and price had to play together in the customers design. With a diverse multi-billion dollar end equipment market available and Burr-Brown's excellent reputation in digital audio, we expect the PCM3000 to be a winning product for us." The PCM3000/3001's ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. core employs delta-sigma modulation with 64X oversampling Creating a more accurate digital representation of an analog signal. In order to work with real-world signals in the computer, analog signals are sampled some number of times per second (frequency) and converted into digital code. , a digital decimation DECIMATION. The punishment of every tenth soldier by lot, was, among the Romans, called decimation. filter, and a high-pass filter. The DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter core employs Burr-Brown's proprietary multi-level delta-sigma architecture which includes an 8X oversampling digital interpolation interpolation In mathematics, estimation of a value between two known data points. A simple example is calculating the mean (see mean, median, and mode) of two population counts made 10 years apart to estimate the population in the fifth year. filter, digital attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. , de-emphasis, infinite zero detection, and soft mute to form a complete subsystem. The PCM3000/3001 was designed using highly advanced 0.6 micron CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology. PCM3000/3001 accepts all industry-standard data formats including left-justified, right-justified, I2S, or DSP, using either 16 or 18 bits. It features a single +5V power supply and can be bitmapped with a three-wire serial interface for special features and data formats. PCM3000/3001 is available in a 28-lead SSOP SSOP Shrink Small Outline Package SSOP Sanitation Standard Operating Procedures (USDA) SSOP Sanitary Standard Operating Procedures SSOP Sharescan-Open Platform (Ecopy) SSOP Site Security Operational Procedures package and priced at $4.39 in 10,000s. Delivery is from stock. Burr-Brown Corp. is a worldwide leader in the development, manufacturing and marketing of electronic components including precision linear, data conversion and mixed signal integrated circuits. These products address applications for both analog and digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). relating to communications, industrial and process control, test and measurement, medical and scientific instrumentation, medical imaging, digital audio and video, multimedia, and personal computer systems.
