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 pickups.
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.
