FN7219.2
Laser Driver Oscillator
The EL6204 is a push-pull oscillator
used to reduce laser noise. It uses the
standard interface to existing ROM
controllers. The frequency and amplitude are each set with a
separate resistor connected to ground. The tiny package
and harmonic reduction allow the part to be placed close to a
laser with low RF emissions. An auto turn-off feature allows
it to easily be used on combo CD-RW plus DVD-ROM pick-
ups.
If the APC current is reduced such that the average laser
voltage drops to less than 1.1V, the output and oscillator are
disabled, reducing power consumption to a minimum.
The current drawn by the oscillator consists of a small utility
current, plus the peak output amplitude in the positive cycle.
In the negative cycle the oscillator subtracts peak output
amplitude from the laser APC current.
The EL6204 part is available in the space-saving 6 Ld SOT-
23 package and is specified for operation from 0°C to +70°C.

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