Hi Paul, Karl and Jim,

Paul, I think you meant the 3340.

Quote from the Datasheet:
"For temperature compensation, the 3374 includes an on-chip temperature
sensor which generates an output voltage, nominally +2.5V, proportional
to chip temperature (i.e., with a TC of +3300ppm); by ensuring that the
exponential control voltage is derived from this sensor output (for
instance, by applying it to the reference input of the system DAC),
unsurpassed oscillator stabilities can be archeived."


Cheers,
  René
