Burr-Brown Announces IC for DVD Applications, Will Lower Overall DVD System Cost.

TUCSON, Ariz.--(BUSINESS WIRE)--Oct. 6, 1997--Burr-Brown Corporation (NASDAQ:BBRC) today announced the low cost PCM1727, a complete stereo audio digital-to-analog converter (DAC) with a dual phase-locked loop (PLL) circuit -- an innovation that lowers the component count of a DVD system and simplifies its design, thus reducing the overall system cost and making DVD more affordable to consumers.

Digital Versatile Disk players are expected to be the next major wave in consumer electronics and rapid reduction in the selling price is needed to accelerate consumer acceptance.

"The PCM1727's dual PLL offers manufacturers both cost and space savings by eliminating discrete components previously needed to generate the audio clocks in a DVD system -- without compromising performance," said Mike Centorino, audio product marketing manager at Burr-Brown. "We worked closely with several of the major DVD manufacturers in Japan in defining the PCM1727 and anticipate quick market penetration."

PCM1727 is ideal for applications which combine compressed audio and video data such as DVD, DVD audio with CD/DA compatibility, and karaoke DSP. The rapidly growing DVD market is expected to reach 11 million units per year by 2000, according to Euromonitor's Strategy 2000 report.

PCM1727's unique on-board programmable dual PLL uses an external 27MHz master clock to derive a variety of audio clocks required in a DVD system -- simplifying the audio clock design in the application. Audio clocks ensure audio/video synchronization and eliminate the need to skip or repeat video frames.

PCM1727 can accept 16-, 20-, or 24-bit input data in either normal or I2S formats. The DAC contains a third-order delta-sigma modulator, a digital interpolation filter, and an analog output amplifier. In addition, it offers 92dB dynamic range, multiple sampling frequencies, and a +5V single power supply.

PCM1727 is priced from $3.61 in 10,000s and is available in a 24-pin SSOP. Delivery is from stock.
