Dual 4-Channel Driver with Oscillator &
LVDS
The EL6833 is a high performance,
dual output, laser driver for writeable
‘super-combo’ CD - DVD drives. The
ENA pin enables the chip, while the SEL1 pin selects the
IOUT pin. Various waveforms can be generated where the
amplitude is determined by the currents flowing into IINR,
IIN2, IIN3, and IIN4. The timing is determined by the signals
at WEN2-WEN2B, WEN3-WEN3B, and WEN4-WEN4B. The
oscillator is enabled when OSEN-OSENB is high. The
amplified IINR current of the selected channel is 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.
Usually a voltage DAC will drive a resistor that is in series
with the IINR, IIN2, IIN3 and IIN4 input. The resistor allows the
user to optimize the current gain for each channel.
Output write current pulses are enabled when a high is
applied to the WEN2-WEN2B, WEN3-WEN3B, or WEN-
WEN4B pin. The write current will flow to the selected
output. When SEL1 is high IOUT1 is selected. WENRB
enables read and oscillator current when low.
The RF oscillators frequency is determined by RFREQ1 or
RFREQ2, and its amplitude by RAMP1 or RAMP2.

NOTE: Intersil Lead-Free products employ special lead-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which is compatible with both SnPb
and lead-free soldering operations. Intersil Lead-Free products are
MSL classified at lead-free peak reflow temperatures that meet or
exceed the lead-free requirements of IPC/JEDEC J Std-020B.
