Laser Driver Oscillator
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-pk controlled with a single resistor · Auto turn-off threshold · Soft edges for reduced EMI · Small 6-pin SOT23 package
General Description
The EL6204C 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. 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 package and is specified for operation from 0°C to +70°C.
