The EL6207 is a dual push-pulloscillator used to reduce laser noise. Itis opTImized for 350MHz operaTIon,allowing reduced concern for harmonic EMI. It uses thestandard interface to exisTIng ROM controllers. Thefrequency and amplitude are each set with a separateresistor connected to ground, for each output. The TInypackage and harmonic reduction allow the part to be placedclose to a laser with low RF emissions.If the voltage at both IOUT pins is less than 1.0V, the chip willbe powered down and not oscillate. If the voltage at eitherIOUT pin is above 1.4V, the chip will be powered up andoscillating. If both IOUT pins are above 1.4V, the chip willalso be powered down, and not oscillate.The current drawn by the oscillator consists of a small utilitycurrent, plus the peak oscillator amplitude in the positivecycle, which is routed to the enabled IOUT pin. In thenegative cycle the oscillator subtracts peak oscillatoramplitude from the laser APC current.The part operates from a single 5V supply, and is specifiedfor operation from 0°C to +85°C.
