Dual Laser Drivers
Intersil's new Elantec® EL683X family is comprised of dual output 4-channel LDDs that offer the performance, flexibility, and power efficiency needed in portable drives supporting all popular disk drive formats, including DVD+R/W, DVD+R, DVD-RW, DVD-RAM, CD-R/W, CD-R, and CD-ROM.
Each device in the EL683X family features dual output stages, one read and four write channels, and two on-chip 600-MHz high frequency modulator (HFM) oscillators that 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 compatibility. All devices include a disable feature for power-up protection and power savings, and all but the EL6836 and 6838 incorporate low-voltage differential signal (LVDS) inputs on the fast switching lines.
