"We continue to add innovative products to our optical storage portfolio that enhance our position as the world's number one supplier of laser diode drivers", said Zhong Li, Marketing Director for Intersil's Elantec Optical Storage Products.
"This new family of write strategy LDDs is the first in the world to address DVD+/-R 8x, DVD R/W 4x and DVD-RAM 3x formats, and will help enable many innovative optical storage platforms including new generations of high-speed disk drives, DVD camcorders and consumer DVD recorders.
Our goal is and will continue to be delivering innovative, flexible laser diode driver architectures that allow our customers to bring their products quickly to market".
All products in the new EL691X LDD family incorporate a waveform generator, simplifying the design of multistandard writable optical drives by integrating all of the timing and power control algorithms required into the device.
Programming is accomplished through a serial interface port and the architecture allows reprogramming of the timing to support different media, DVD or CD standards, and different speeds.
Programmable waveform values support 2.6Gbyte DVD-RAM, 4.7Gbyte DVD-RAM, DVD-R, DVD+R, DVD+RW, DVD-RW, CD-RW and CD-R.
Two analogue inputs on each device in the EL691X family support slope and read adaptive power control (APC).
An integrated high-frequency modulator (HFM) oscillator is programmable to 100mA peak-peak from 200 to 500MHz.
Each device incorporates two laser outputs to support read/write DVD and CD combinations and offers 100ps timer resolution.
