Intersil introduced a new family of dual laser diode drivers (LDDs) optimized for low power, slim CD and DVD recordable disk drives used in laptop PCs. Intersil’s new Elantec® EL683X family is comprised of dual output four-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 Megahertz 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 in the EL683X family 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.
EL683X Key Features
· One read and four write channels with two integrated high frequency modulators (HFMs)
· On-chip 600 MHz HFM oscillators allow dual output current modulation in any mode
· Oscillator amplitude to 100 milliamps peak to peak
· Switching speed of 0.8 nanosecond typical rise/fall time
· Single +5V supply (+/-10%)
· Disable feature for power-up protection and power savings
· 32-pin leadless plastic package
Availability and Pricing
Intersil's Elantec EL6833, EL6834, EL6835 and EL6839 are available now in a 32-pin leadless plastic package (LPP) for $1.50 each in 10,000-unit quantities. The EL6836 and EL6838 do not include LVDS signal inputs and are available in a 32-pin LPP and 24-pin LPP, respectively, for $1.50 each in 10,000-unit quantities.
