"..Elantec Semiconductor today announced the release of its EL6290C, a next-generation laser driver designed to enable optical drives to both write and read either DVD or CD disks. The EL6290C is the result of a joint development between Elantec Semiconductor and the Digital Media Products Division of Hitachi. The EL6290C supports multi-standard DVD formats: 4.7GB DVD-RAM, 2.6GB DVD-RAM, DVD-R, DVD-RW, +RW and DVD-ROM, as well as CD formats: CD-RW, CD-R and CD-ROM.
The EL6290C is a programmable laser driver engine that integrates the write strategy waveforms that support a wide variety of industry standard DVD and CD formats, media, and write speeds. The EL6290C contains waveform amplitude and timing registers that are programmable through the serial interface that configures the internal EL6290C's waveform generator. The EL6290C contains two high current outputs that enable either of two lasers to either write or read both the DVD and CD formats. Other features include a programmable high-frequency oscillator, a low noise read amplifier, a programmable laser slope compensation DAC, and programmable laser threshold current DAC..."
