PRELIMINARY
Dual Laser Driver
Features
• “Shrink-small” outline package
The EL6830 is a combination read +
2 write level laser driver with an extra
• Voltage-controlled output current source requiring one
external set resistor per channel
read + oscillator ROM channel for
use in dual-laser ‘combo’ drivers. A separate (amplitude and
frequency) oscillator modulates the selected output for laser
noise reduction during read or write. All these functions are
provided in a 16-pin QSOP package.
• Current-controlled output current source
• CH2 to 300mA max
• CH3 to 150mA max
The CD pin, when high, selects the CD (write) laser. Positive
• Rise time = 0.8ns
current supplied to the I lines, through a user-selected
IN
resistor, allows the full scale range of each amplifier to be
matched to the full scale range of the users control DACs.
When the write laser is selected, and the WEN pins are
switched low, the respective current is summed to the output
with 1ns rise and fall times. Write channel 2 has 300mA
output capability with a 300X gain amplifier.
• Fall time = 0.8ns
• On-chip oscillator with frequency and amplitude control by
use of external resistors to ground
• Oscillator to 600MHz
• Oscillator to 100mA pk/pk
• Single +5V supply (±10%)
The 100mA
(max) oscillator is switched on and off
P-P
automatically when WEN2 and WEN3 are pulled high.
• Disable feature for power-up protection and power
savings
The entire chip is powered down when ENABLE is low.
Applications
• Combo CD-RW + DVD-ROM
• CD-RW to 20X
• CD-R to 48X
• Writable optical disk drives
