Discrete OCXO | Standard OCXO with thermal compensation The ROX3827T3 OCXO is the cost effective highly stable oscillator for telecom applications. The performance over temperature range is comparable to the current ROX-T2. Its total stability is down to less than 50 ppb per year across all causes. Frequencies available are from 5MHz to 40MHz, and power supply options are 3.3V, 5V & 12V. These 38 x 27 mm package series of oscillators are designed with an embedded post-compensation system with a micro-controller. They are optimized designs for the Stratum 3E and up to Stratum 2. Applications ■ IEEE 1588: G.8263, G.8273.X ■ Stratum 3E timing modules ■ Stratum 2 stability ■ Time and frequency references ■ Wireless Base Stations ■ LTE-TDD Base Stations Features ■ Hold over below 7 ps /15 ps over 24 hours, including temperature changes ■ Standard frequencies: 10, 12.8, 13, 20, 24.576, 26 and 40 MHz ■ Small form factor ■ Temperature sensor output ■ 2 packages height : 11.7 mm and 17 mm Parameter Min.
