Applications Information
Product Description
The EL6202 is a solid state, low-power, high-speed laser
modulation oscillator with external resistor-adjustable
operating frequency. It is designed to interface easily to laser
diodes to break up optical feedback resonant modes and
thereby reduce laser noise. The output of the EL6202 is
composed of a push current source switched at the oscillator
frequency. The output and oscillator are automatically
disabled for power saving when the average input current
drops to less than 100μA. The EL6202 has the operating
frequency from 60MHz to 600MHz and the output current
from 10mA
P-P
to 100mA
P-P
. The supply current is only
30mA (includes laser current) for the output current of
50mA
P-P
at the operating frequency of 350MHz.

Either the high current controller resistor can be
reduced to 2mA full scale, or the transistor and resistor
can be replaced with a resistor from the controller DAC.
