SUNNYVALE, Calif.--Oak Technology Inc. here today moved into the market for analog frontend controllers in compact disk recordable/rewritable (CD-R/RW) drives with the launch of a new CMOS device that supports up to 12x write and 40x read performance.
Oak Technology said its new OTI-9071 controller integrates all the major components of the analog frontend function, including radio-frequency amplifier, sample and hold module, absolute time in pre-groove (ATIP) extraction, write digital-to-analog converter, and automatic power calibration DAC. The company also said additional component integration was possible because the controlloer architecture employs a "bottoms-up" system-on-chip design methodology.
In total about 100 external discrete components are eliminated by the CMOS analog frontend controller, said the Sunnyvale company.
"The CD-RW drive market is exhibiting extremely high growth, with yearly volume projected to exceed 42 million units by the year 2001 according to IDC International Data Corp.," said Bill Housley, vice president and general manager of Optical Storage Group at Oak. He said the addition of the new analog frontend controller and the company's existing OTI-9071 servo processor DSP controller positions Oak Technology well for the emerging CD-RW drive market.
The new CMOS analog frontend controller dissipates less than 700 milliwatts while operating, about one-third of the competing devices, according to Oak. In stand-by mode, the chip consumes 10 mW.
The OTI-9071 is housed in a 100-pin low-profile quad flat package (LQFP). The device will sell for $6.50 each in quantities of 10,000. Samples are available now with volume production set to start in early summer.
