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.
