NEC develops 8X DVD writer chipset

The chipset comprises the µPD63630, a DVD signal processor with ATAPI interface, and the µPC3330, an analog signal processor that controls the servo system of the optical pickup. Compliant withvarious recording formats such as DVD-R/RW, DVD+R/+RW, and DVD-RAM, the new chipset will enable OEMs to easily configure a DVD rewritable drive capable of handling all the major standards. (Thespecification for 8x DVD-R recording is currently going through the standardization process at the DVD Forum.)

In the µPD63630, NEC Electronics provides high-speed recording through fast data processing and built-in write functions capable of controlling the recording laser power with high precision. The high-bandwidth amplifier adopted in the µPC3330 also contributes to stable recording at 8x speed for DVD-R and DVD+R.

The µPD63630 achieves high-speed recording while significantly reducing power consumption by taking advantage of 0.15-micron process technology and optimizing clock frequency in each block of the chip. In the µPC3330, the circuit configuration is optimized to reduce amplifier current, which reduces the device’s power consumption. As a result, the chipset has achieved a power consumption rating approximately 30% lower than earlier devices.

As an additional benefit, the new chipset also provides 2x DVD-RAM read capability that enables it to read all of the DVD recording formats currently available on the market, including DVD-R/RW, DVD+R/+RW, and DVD-RAM.

“We expect the sales of DVD drives for the PC market to triple in 2003 from the previous year,” said Shigeo Niitsu, general manager, 2nd System LSI division, NEC Electronics Corporation. “The increasing demand to store more data in the broadband networking environment will continue to expand the DVD drive market, even among consumers. Accordingly, NEC Electronics has introduced this high-performance chipset to meet the demands of this expanding market.”

The chipset is expected to be used by Pioneer Corporation and NEC Corporation for their new rewritable DVD drives. Both companies are among the world’s leading manufacturers of DVD writers.

The µPD63630 and µPC3330 are both housed in thin-type quad flat packages (QFP) while increasing function and performance, which also makes the chipset suitable for a slim DVD drive.

NEC Electronics will exhibit the chipset at CEATEC JAPAN 2003, a major show covering communications, information and video, that will be held at Makuhari Messe, Tokyo, Japan, starting October 7.

Pricing and Availability
Engineering samples of the chipset will be available at the end of this month at US$35 each. The monthly mass production volume is expected to reach 2 million pieces in March 2004. Prices subject to change.
