Intersil Unveils New Higher Speed Laser Driver for DVD/CD Dual Writer Optical Disk Drives.Business Editors/High-Tech Writers IRVINE, Calif.--(BUSINESS WIRE)--Oct. 1, 2002 EL6229C Dual Laser Diode A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core Driver Increases Speeds Up to 52X In Existing CD-R/W Designs; Combines Superior Performance With Pin-for-Pin Compatibility Intersil Corporation (Nasdaq:ISIL ISIL International Society for Individual Liberty ISIL Interim Support Items List ISIL Intelligence Systems Integration Laboratory (Ft. Huachuca, Arizona; US Army facility for integrating intelligence systems) ), a world leader in the design and manufacture of high performance analog and wireless networking See wireless network. solutions, today unveiled a new dual laser diode driver designed specifically to enable read (CD-R (CD-Recordable) A writable CD technology using a type of compact disc that can be recorded, but not erased (CD-Rs are "write once" discs). CD-R discs are used to master CD-ROMs, to back up data and to make copies of data for distribution. ) and read/write (CD-R/W) speeds up to 52X in laser disk drives. Intersil's new EL6229C dual three-channel laser driver enables optical disk drive manufacturers to increase the performance of existing designs or quickly develop a DVD/CD dual writer driver from a single CD writer drive design. "The EL6229C is the latest addition to a portfolio of CD and DVD recordable DVD recordable and DVD rewritable refer to DVD optical disc formats that can be recorded (written, "burned"), either or rewritable (write multiple times) format written by laser, as compared to DVD-ROM, which is mass-produced by pressing. products that have made Intersil the number one laser driver IC supplier in the world. Our latest offering, a dual laser driver that provides outputs for both a CD and DVD DVD: see digital versatile disc. DVD in full digital video disc or digital versatile disc Type of optical disc. The DVD represents the second generation of compact-disc (CD) technology. laser, allows customers a quick upgrade path to better waveform fidelity, better performance and higher speed CD-R and CD-R/W drives," said Stephen P. Sacarisen, director of Strategic Marketing for Intersil's Elantec Optical Storage Products. "The EL6229C is pin-for-pin compatible with our EL6119, but offers the superior performance of our new EL622XC family, enabling read and read/write speeds up to 52X in CD-R/W laser disk drives. Like the other products in our EL622XC family, the EL6229C reduces component count, shortens signal routing and enables more compact optical pickup designs." Intersil's EL6229C is a dual three-channel (one read and two write levels) laser driver that provides improved current control to both the CD and DVD laser diodes. Each channel has a separate enable pin for the DVD or CD driver output. This simplifies control and gives 100 percent compatibility with existing single channel designs. Like other devices in Intersil's new EL622XC family, the EL6229C provides improved waveform fidelity, increased output current, lower power dissipation and reduced noise to enable higher speed CD-R/RW and DVD designs. The EL6229C has an on-chip 600 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air to allow frequency and amplitude control by use of external resistors to ground. The external resistors allow customers to accurately and independently set each amplifier transconductance by applying a voltage to the resistor without restriction on the voltage range, thus ensuring broad voltage DAC See D/A converter and discretionary access control.

The EL6229C is compliant with the industry-standard Orange Specification for CD-R and CD-R/W write strategy disc formats at speeds up to 52X and all DVD formats There are several competing DVD Formats: Non-recordable formats
