The new OCXO also provides a better design choice than the traditional technique of up-converting from a 10MHz OCXO as that approach tends to cause significant degradation in
phase-noise performance and reduce the overall signal-to-noise ratio of the system.
Phase noise for the XO5085 is specified as -100dBc @ 10Hz offset and -170dBc @ 10kHz offset. It is a 12V device with a maximum steady-state power consumption of 1.5W and an operating temperature range of 0 to 80degC.
Housed in a hermetically sealed package measuring just 26.2 x 26.2 x 12.7mm high, the OCXO meets the decreasing size and lower cost requirements of portable and airborne systems and is particularly suitable for instrumentation, microwave radio, EW, satcom and radar applications.
