A precision oven-controlled crystal oscillator (10) uses an adjustment feedback signal that, when mixed with a reference signal from a stable reference oscillator (32), accurately controls the generation of an output signal from a voltage controlled crystal oscillator (38). An OCXO according to the invention has high stability and high accuracy. The digital OXCO can be manufactured at low cost, and is particularly beneficial for Code Division Multiple Access (CDMA) base station applications in cellular communication networks and the like.
