EL6200C - Product Brief
450 MHz HFM Oscillator
Features
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
The EL6200C is a solid state high performance laser modulation oscil-
lator 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.
• Simple to use - only two external
resistors required
• Independent resistor setting for
frequency and amplitude.
The oscillator frequency is set by connecting a single external resistor
from the RFREQ pin to ground. The oscillator current output ampli-
tude is set by connecting a single external resistor from the RAMP pin
to ground.
The EL6200C has internal supply bypass capacitors to reduce oscilla-
tion noise spread through supply connections.
