PRELIMINARY
Dual 4-Channel Driver with Oscillator
Features
• Two channels for CD or DVD
The EL6836 is a high performance,
dual output, laser driver for writeable
DVD drives. The ENA pin enables the
• Voltage-controlled output current source requiring one
external set resistor per channel
chip, while the SEL1 pin selects the I
OUT
pin. Various
• Rise time = 0.8ns
waveforms can be generated where the amplitude is
determined by the currents flowing into I , I , I , and
INR IN2 IN3
• Fall time = 0.8ns
I
. The timing is determined by the signals at WEN2B,
IN4
WEN3B, and WEN4B. The oscillator is enabled when OSEN
is high. The amplified I current of the selected channel is
• Channel 2 to 250mA max
• Channel 3 to 150mA max
• Channel 4 to 100mA max
INR
enabled when the ENA pin is high. The total output current is
the sum of the read current, the enabled write currents, and
the oscillator current when enabled.
• On chip oscillator with frequency and amplitude control by
use of external resistors to ground
Usually a voltage DAC will drive a resistor that is in series
• Oscillator frequency to 600MHz
with the I
, I , I , and I
input. The resistor allows

the user to optimize the current gain for each channel.
• Oscillator amplitude to 100mA
• Single +5V supply (±10%)
• Chip ENAs for power savings
P-P
WEN2B, WEN3B, and WEN4B are CMOS input pins with a
1.68V threshold. Output write current pulses are enabled
when a low is applied to the WEN2B, WEN3B, or WEN4B
pin. The write current will flow to the selected output. When
