Abstract
This paper reports on a development and tests of the DSP-OCXO (Digital Signal Processing-Oven Controlled Crystal Oscillator) using AT cut crystal high accuracy temperature sensor which consisting of two thermal equivalent crystals. For the applications of the small size base stations, the DSP-OCXO which has following features: 14 × 9 mm small size, 0.6 W maximum at +25°C low power consumption and +/-20 ppb maximum /-40 to +85°C high frequency stability vs. temperature has been developed.
