Dual 4-Channel Laser Diode Driver +
Oscillator
Features
• Leadless plastic package
The EL6119 is a dual four-channel
laser diode current amplifier that
provides controlled current to both a
• Voltage controlled output current source, requiring one
external set resistor per channel
• Rise time = 0.8ns
• Fall time = 0.8ns
CD and DVD laser diode. Channels 2, 3, and 4 should be
used as the write channels, with switching speeds of
approximately one nanosecond rise/fall time. All four
• On chip oscillator with frequency and amplitude control by
use of external resistors to ground
channels are summed together at the I
output, allowing
OUT
the user to create multilevel waveforms in order to optimize
laser diode performance. The level of the output current is
set by an analog voltage applied to an external resistor
which converts the voltage into a current at the I pin
(virtually ground). The current seen at this pin is then
• Oscillator to 500MHz
• Oscillator to 100mA
PK/PK
IN
• Single +5V supply (±10%)
amplified to become a current source at pin I
.
• Disable feature for power-up protection and power savings
• CMOS control signals
OUT
Output current pulses are enabled when an ‘L’ signal is
applied to the WEN pin. No output current flows when WEN
is ‘H’ and additional laser diode protection is provided since
Applications
the WEN input will float high when open. Complete I
shutoff is also achieved by holding the ENABLE pin low,
which will override the WEN control pins.
OUT
• CD + DVD Combo applications
• Writable optical drives
• Laser diode current switching
Each laser driver has a separate ENABLE pin to allow total
shutdown of each laser driver when not in use.
An on-chip 500MHz oscillator is provided to allow output
current modulation when in read mode. The oscillator is
enabled when the OSCEN pin is held high. Complete control
of amplitude and frequency is set by two external resistors
connected to ground at pins R
and R
(see graphs
