Dual Laser Driver Oscillator

The EL6207 is a dual push-pull oscillator used to reduce laser noise. It is optimized for 350MHz operation, allowing reduced concern for harmonic EMI. It uses the standard interface to existing ROM controllers. The frequency and amplitude are each set with a separate resistor connected to ground, for each output. The tiny package and harmonic reduction allow the part to be placed close to a laser with low RF emissions.

Features

• Low power dissipation

• User-selectable frequency from 100MHz to 600MHz controlled with a single resistor for each laser

• User-specified amplitude from 10mAPK-PK to 100mAPK controlled with a single resistor for each output

• Auto turn-off threshold

• Soft edges for reduced EMI

• Small 8-pin LPP package

Applications

• Combi drive using dual laser
