SANYO Electric Co. LTD announced a new LSI chipset that supports DVD±R/RW, CD-RW and HD-BURN format with the codename "LC897390K". The new chipset can be used for optical storage devices that will include high recording and reading speeds. The massive production expected to start in January 2003 with a sample price of 3.000 Yen. The CRD-BPD2 is a drive that already uses it. Lastly, SANYO believes that the DVD+R will finally dominate over DVD-R, at least for the home DVD recorders...
As SANYO comments "...Although CD-R / RW drive spread widely as an object for data preservation of a personal computer, the needs of the DVD record drive in which more nearly mass record is possible are increasing by the spread treating image data, such as a digital camera, of products in the market.
Our company for the first time supports both DVD±R/RW and HD-BURN. The Signal processing LSI LC897390K corresponding to the record reproduction system were developed. It becomes possible [ performing all signal processings required for a DVD±R/RW drive with two tips of LC897390K and RF amplifier ], and the large rationalization design of a drive is attained.
LC897390K consisted of blocks of CD encoder / decoder, a CD-ROM encoder / decoder, a DVD encoder / decoder, an ATIP/ADIP/LPP circuit, digital servo, the light strike RATEJI function that raises record grace by optimal record control, an ATAPI interface, etc., and in order to realize low power consumption, they were developed in 0.25micromCMOS process. An outside is the 256 pin LQFP.
Not only record reproduction of DVD±R/RW but record reproduction of CD and CD-ROM is possible for newly developed LSI. In DVD±R/RW record, it corresponds to 5X record of the industry highest level, and DVD reproduction corresponds to 16X by correspondence, CD, and CD-ROM record, and corresponds to 48X in 40X record, CD, and CD-ROM read-out. Furthermore, BURN-Proof which avoids the error at the time of record ※2 And since HD-BURN which realizes record by twice as many capacity as this is carried in CD-R / RW media, differentiation of a DVD record drive is attained.
Moreover, since Book LSI can be used also for a noncommercial DVD recorder, it becomes same [ that a DVD recorder realizes HD-BURN record etc. ] to drive the differentiation of apparatus of it for personal computers possible.
