Typical Application Circuit
Applications Information
The EL6201 is designed to interface easily to laser diodes to
break up optical feedback resonant modes and thereby
reduce laser noise, but it is also generally useful as a 70MHz
- 430MHz oscillator. The first applications section will focus
on laser systems, and subsequent sections are of general
topics.
Laser Diode Applications
The output of the EL6201 is composed of a sourcing and a
sinking current source, switched alternately at the oscillator
frequency. The output voltage compliance is V
S
to ground,
with about 40
of series resistance. There is no severe
squarewave distortion when the output voltage approaches
the supply extremes, although the corners will be rounded.
Being a current-source output, the output bias voltage is set
by direct connection to the laser diode, which will appear as
a low AC impedance with a DC voltage from 1.6V to 2.5V.
Thus AC coupling from the EL6201 to the diode is
unnecessary. The duty cycle of the output is between 40%
and 60%, so the DC contribution from the EL6201 is only
±5% of the peak-to-peak output. This will cause little
perturbation of the diode’s DC bias current.
Although not necessary, capacitance coupling can be
employed. A series capacitive reactance of less than 30
is
recommended. A 20pF capacitor is thus appropriate at
330MHz. Benefits include no DC error current into the laser
diode, and an attenuation of low-frequency noise from the
EL6201. Disadvantages include perhaps 20% output AC
current loss.
While the diode AC impedance is generally in the low ohm
range, any interconnect will create around 8nH per cm. of
series inductance. Because the EL6201’s output is an AC
current source, higher load reactance due to series
inductance will cause the EL6201’s output voltage to swing
more than what a direct connection to the diode would
cause. At 400MHz and 15mA
P-P
output, just one cm. will
generate 0.3V
P-P
of extra driver signal at the fundamental,
and more at harmonic frequencies. The output current
