General Description
The EL6202C 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.
The total current drawn from the power supply can be less than the laser
threshold current due to the unique push-only modulation method. The
average current is less than the peak oscillator current, and can be less
than half of the oscillator current. The power control current supplied
from the main board is reduced from many tens of mA to less than
2mA.
One external resistor sets the oscillator frequency. A current applied to
the IIN terminal determines the amplitude of the oscillator and laser DC
current. If the oscillator amplitude is set very low, the output and oscil-
lator are disabled. The part is available in the space-saving SOT23-5
package. It is specified for operation from -0
°C to 70°C.
