General Description
The EL6204C is a push-pull oscillator used to reduce laser noise. It
uses the standard interface to existing ROM controllers. The fre-
quency 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 fea-
ture 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 EL6204C part is available in the space-saving 6-pin SOT23 pack-
age and is specified for operation from 0
°C to +70°C.
