adjust initial operating points, but they should be replaced
with fixed resistors for further testing.
External voltage sources can be coupled to the R
AMP
and
R
FREQ
pins to effect frequency or amplitude modulation or
adjustment. It is recommended that a coupling resistor be
installed in series with the control voltage and mounted
directly next to the EL6201 pin. This will keep the inevitable
high-frequency noise of the EL6201’s local environment from
propagating to the modulation source, and it will keep
parasitic capacitance at the EL6201 pin minimized.
Both inputs have several megahertz of bandwidth for analog
modulation. The output enable pin can be used to pass
digital modulation up to about 20Mbit/sec rates.
Power Dissipation Considerations
Supply current can be predicted by the equation:
The 12mA quantity represents the operating DC current of
the EL6201. This is also the current drawn from the supply
during output disable. The I
OUT
quantity is based on a
typical 50% duty cycle of output pull-up current, and the fact
that the peak-to-peak output current is about twice the pull-
up or pull-down currents. The V
S
quantity is due to CV
2
F
losses within the circuit, and the 8*10
-12
quantity represents
internal capacitances that must be slewed at the operating
frequency. The 1.6V offset is a curve fit to measured data.
The internal die temperature operating range is -40°C to
+125°C. Internal temperature is equal to the ambient
temperature plus power dissipated times the thermal
resistance of the mounted package,
θ
JA
. For a mounted
MSOP-8 package,
θ
JA
is 206°C/W. The SOT-23 package
has a
θ
JA
of 256°C/W.
Power-Down with the SOT-23 Package
The supply current of the EL6201 is low enough so that a
logic output can simply provide the supply current of the part
and effect power-down. This is most useful using the EL6201
in the SOT-23 package, which has no enable pin.
RF Applications
The EL6201 can easily interface to reactive loads, and is
adequate as a short-range modulated transmitter.
Remembering that the output circuitry looks like current
sources, impedance matching becomes a matter of
transforming the load impedance to an appropriate load line
for the EL6201. Also important is maintaining correct DC
bias voltage on the output. Since the output will have a net
DC current, capacitor coupling would allow the DC level to
drift toward a supply rail and increase output harmonic
products. In cases where such harmonics are important,
Figure 25 shows coupling the EL6201 output to a 50
load:
Digital Clock Applications
The EL6201 can be used as a digital clock source. If
unloaded, the output will simply traverse ground to V
S
. It is
recommended that the V
S
supply be isolated from the main
digital supply with an inductor or resistor, whose value is
chosen to drop about 250mV. In this way logic noise can be
isolated by the series component and the EL6201 local
bypass.
The rise- and fall-time of the output will be equal to
V
S
/(C
LOAD
*I
OUTp-p
/2). The output current should be the
smallest that can set an output rise-time, in the interest of
lowest dissipation.
The jitter is about 0.7% of period, RMS.
