Digitimes reports that Panasonic has developed a chipset that support DVD-R and DVD-RAM and this at the speed of 4x. The chip also incorporates new technologies such as a write strategy control technology with pico-second order accuracy, digital signal processing employing a proprietary PRML and digital PLL developed by Matsushita and high-speed signal processing technology that can realize sampling servo method.
The new chipset consists of one chip implementing analog processing functions, such as servo and laser power control, and a second chip that provides optical disc controller functions. Products incorporating this chipset will be able to deliver DVD and CD recording and playback capabilities at the highest level now available in the industry. Supported functions include 4x DVD-RAM, 4x DVD-R/RW and CD-R/RW with 24/16x recording. |
A PRML (partial response maximum likelihood) read channel enables high-speed playback capability and excellent data read accuracy, achieving 16x DVD-ROM and 48x CD-ROM performance. In addition, the chipset can support most kinds of optical pickup systems.
