OCXO

      OCXO OX6749 MODEL has 3 festures.The first one is that it makes low noise.The second one is that it owns excellent frequency stability.The third one is about mechanical / electrical frequency adjustment available. It can be applied to SATCOM,BASE STATIONS,TEST INSTRUMENTS and so on.
      The following are the parameters of OCXO.Oscillator Supply voltage, nom.is 12V ±5% as the same as Oven Supply voltage, nom.Power dissipation steady state is 3 Watt Max.Heat up power is 6 Watt Max.Heat up time. max.(relative to 2 hours after turn on, following 24 hours off) is 3 min Max(Measured at 25°C to within 0.1PPM of final frequency).Frequency is 10MHz.Frequency Adjustment:Electrical (0 to 10V)Mechanical corresponds to 0.6 PPM Min which is enough to compensate for 10 years of aging.Freq. stability vs. temperature LZ: 0°C to 70°C should be within ±0.01 PPM(Standard, contact factory for different temp ranges and stabilities).Freq. stability vs. supply changes shoule be within ±0.002 PPM Max for ±5% Change as the same as Freq. stability vs. load changes.Long term stability (Aging) as follows:±0.7 PPM Max for 10 Years,±0.1 PPM Max for 1 Years,±0.0005 PPM/Day Max.Input Impedance Control Voltage pin is 10K.Output is Sine +7dBm.Harmonics, Sub Harmonics corresponds to  -30dBc(Sine Output).Spurious is -75dBc(Sine Output).Short term Stability corresponds to 1 E-11 /Sec.At last it is the Phase Noise
(Sine Output 10MHZ):10Hz of Offset corresponds to -130 dBc/Hz of Phase Noise.100Hz corresponds to -152 dBc/Hz.1000Hz corresponds to -160 dBc/Hz.10000Hz corresponds to -165 dBc/Hz.100000Hz corresponds to -165 dBc/Hz.
