Abstract
CEPE has recently developed a family of analog temperature-compensated crystal oscillators (TCXOs). These designs use a digital method of thermal compensation to achieve a frequency stability of +or-2*10/sup -6/ under all operating conditions (temperature, power supply, load, one-year aging) with an ultralow power consumption (300 mu A, 3V). Studies of system requirements and analog TCXO capabilities led to the development of TCXOs using a numerical method for thermal compensation called digital temperature compensated crystal oscillator (DTCXOs). The method used to realize the digital compensation and the results obtained on a first batch of DTCXOs are presented.<>
