Modems used in consumer grade electronics need a signal to alert the user that the temperature range of the product has been exceeded. This invention uses the circuitry already in use for the temperature compensation circuit of the reference oscillator used in an existing synthesizer IC to also provide a tem- perature indication signal at low and high tempera- ture extremes.
