450 MHz HFM Oscillator
General Description
Small 5-pin SOT-23 package
Frequency to 450 MHz typ.
Amplitude to 100mA pk/pk typ.
Single +3.5V to +5.0V supply
Simple to use - only two external
resistors required
• Independent resistor setting for
frequency and amplitude.
The EL6200C is a solid state high performance laser modulation oscillator with external resistor adjustable frequency and amplitude. The
EL6200C is available in the 5-pin SOT23 to enable device placement
close to the laser for reduced EMI signature.
The EL6200C has internal supply bypass capacitors to reduce oscillation noise spread through supply connections.

The oscillator frequency is set by connecting a single external resistor
from the RFREQ pin to ground. The oscillator current output amplitude is set by connecting a single external resistor from the RAMP pin
to ground.
