Pioneer Selects Intersil Laser Diode Driver For New Dual-Format DVD and CD Internal Writer
Posted Mar 23, 2004

Intersil Corporation, a world leader in the design and manufacture of high performance analog solutions, has announced that Pioneer Corporation is using Intersil's EL6934 laser diode driver (LDD) in Pioneer's newly-introduced DVR-A07, a dual format DVD/CD internal writer.

The DVR-A07 is Pioneer's first 8X dual format writer, capable of writing at 8X speed on DVD-R and +R discs designed for this recording speed. It also records high speed DVD-RW and +RW discs at up to 4X speed, and CD-R and CD-RW discs at up to 24X speed. Pioneer is helping to eliminate format confusion by supporting the DVD Forum's DVD-R and DVD-RW disc formats as well as the +R and +RW formats. The EL6834 is a dual-output, four-channel LDD for portable drives that supports all popular formats. It provides the current channels required to read, erase, and write information onto CDs or DVDs in the DVR-A07.

Intersil's EL6934 laser driver IC is a highly integrated programmable LDD with built-in waveform generator designed to support different media, DVD or CD standards, and different read/write speeds. It precisely controls the analog voltage applied to the laser diode in Pioneer's DVR-A07 so the laser accurately reads, erases, or writes information onto a CD or DVD.
