Laser Driver Oscillator

The EL6205 consists of a variable amplitude, push only, oscillator that also supplies the laser DC current. It is designed to easily interface to existing ROM controllers, reducing parts count, and power dissipation.

The reduction of parts count and the small package allows the oscillator to be placed closer to the laser, thus reducing EMI. Also, the turn-on and turn-off edges are slew rate limited to reduce higher harmonics.

特性 Features

• Low power dissipation

• Reduced parts count from the conventional solution

• User-selectable frequency from 60MHz to 600MHz controlled with a single resistor

• User-selectable amplitude from 15mAPK-PK to 100mAPK-PK controlled by 0.3mA to 2mA input current

• Auto turn-off threshold

• Soft edges for reduced EMI

• Small 6-pin SOT-23 package

Applications

• DVD players

• DVD-ROM drives

• Combo drives

• MO drives

• General purpose laser noise reduction

• Local oscillator capability
