ALTERNATIVE METHODS OF SETTING THE OUTPUT
FREQUENCY OF THE LTC6905
The LTC6905 may be programmed by any method that
sources a current into the SET pin (Pin 3). The accuracy of
the programming is best with a simple resistor because
the LTC6905 takes into account both the voltage at the SET
pin and the current into the SET pin when generating the
output frequency. Since the voltage at the SET pin can vary
by as much as 5%, setting the frequency using a current
rather than a resistor will result in as much as 5% addi-
tional inaccuracy in the output frequency.
Figure 3 shows a method to control the frequency of the
LTC6905 using a current source. R
SET
, in this case, sets a
maximum frequency according to the regular expression
for f
OSC
. The current source will subtract current from the
SET pin to lower the frequency.
Figure 4 shows a method for controlling the frequency of
the LTC6905 using a voltage source. In this case, R
SET
sets
a constant current into the SET pin, and R
CNTRL
will sub-
tract from this current in order to change the frequency.
Increasing V
CNTRL
will increase the output frequency.
