General Description
The EL6203C 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.

Features
• Low power dissipation
• User-selectable frequency from 60MHz to 600MHz controlled with a single resistor
• User-specified amplitude from 10mA pk-pk to 100mA pk controlled with a single resistor
• Auto turn-off threshold
• Soft edges for reduced EMI
• Small 5-pin SOT23 package

Applications
• DVD players
• DVD-ROM drives
• CD-RW drives
• MO drives
• General purpose laser noise reduction
