Dual Push-Pull Laser Driver Oscillator

The EL6208 is a dual push-pull oscillator used to reduce laser noise in twin laser diodes. It uses the standard interface to existing ROM controllers. The frequency and amplitude are both 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 activates the oscillator only when the APC current is applied.

FEATUREs
• Low power dissipation
• User-selectable frequency from 60MHz to 600MHz controlled with a single resistor
• User-specified amplitude from 10mAPK-PK to 100mAPK-PK controlled with a single resistor
• Auto turn-off threshold
• Soft edges for reduced EMI
• Small 6-pin SOT-23 package

APPLICATIONs
• CD-DVD ROM drives
