NEC Electronics
Corporation and its subsidiaries in the United States and Europe, NEC
Electronics America, Inc. and NEC Electronics (Europe) GmbH, today
announced they have developed a new chipset for rewritable DVD drives
supporting an 8x recording speed in DVD-R and DVD+R formats.
The chipset comprises the uPD63630, a DVD signal processor with ATAPI interface, and the uPC3330, an analog signal processor that controls the servo system of
the optical pickup. Compliant with various 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. (The specification for 8x DVD-R recording is currently going
through the standardization process at the DVD Forum.)
In the uPD63630, 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 uPD63630 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 uPC3330,
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.
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 uPD63630 and uPC3330 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.
