ABSTRACT:
A method provides a temperature controlled frequency source. The method reduces the effects of temperature variations on an operating frequency of the temperature controlled frequency source by temperature compensating the temperature controlled frequency source. The temperature-controlled frequency source may be an Oven-Controlled crystal oscillator (DCXO) and the temperature-controlled frequency source may be a TCXO ASIC. Analago temperature compensation may be provided by generating zero to fourth-order polynomial Chebyshev functions of temperature.
