OVC3CF4AA

      The OVC3CF4AA which is connor-winfield is a 3.3V voltage controlled oven controlled crystal oscillator(OCVCXO) with an LVCMOS output. Also the OVC3CF4AA is designed for stratum 3E applications which requiring low jitter and tight frequency stability.
      OVC3CF4AA has seven features.The first one is that it designed to meet stratum 3E requirements.The second one is that it has the function of variable frequency(OVCCXO).The third one is about the frequency stability which should be within +/-10ppb.The fourth one is about the temperture range which should be from -40 to 70°C.The fifth one is that it would be 3.3V operation.The sixth one is that it has the LVCMOS output.The last one is RoHS 5/6 compliant.
      The absolute maximum ratings of OVC3CF4AA have been concluded as three points.The minimum of storage temperature is -55°C while the maximum of it is 125°C.The minimum of supply voltage is -0.5(Vcc) while the maximum of it is 4.5(Vdc).The minimum of input voltage is -0.5 while the maximum of it is Vcc+0.5(Vdc).
      There are also some notes about OVC3CF4AA.The first one is that labels will include the calibration frequency at the time of ship.The second is initial calibration @ 25 C, Vc=1.65Vdc, at time of shipment.The third one is frequency vs. temperature stability, referenced to 25 C.The tourth one is that it would have ten days of continuous operation.The fifth one is allen variance: 1 second, 100 average.The sixth one is that Vcc would be equal to 3.3Vdc,that means Vcc=3.3Vdc.The seventh one is that if from Vcc=90% of final value, no more than 16 transitions at start-up before oscillator has started.The eighth one is that it would be measured @ -40 C, within 5 minutes, referenced one hour after turn-on.The ninth one is that after stabilization in a controlled airflow environment.The tenth one is that at time of delivery.The eleventh one is that it has the LVCMOS load.The twelveth one is that if for a given off time, the time required to meet daily aging, short-term stability and TDEV requirements.
