Control Voltage Current Draw for OCXO?

[t1d]

I have purchased an OCXO. The data sheet states that the unit operates on 5V and draws a maximum of 600mA, upon start up. The voltage for the frequency adjustment is +/-2V. However, the current draw for the frequency adjustment voltage is not stated in the data sheet. Should I assume this draw to be the same as the working voltage, as much as 600mA on start up? Thank you for your help.

Line 21:  the input impedance at the voltage control is specified as 100 k , wherefore the current drain should be around 20 uA at 2.0 V.

Excellent; thanks Tim. I think that I have also been misinterpreting the control voltage as +/-2V. At a ambient temperature of 25C, the needed control voltage is +2V = ~0 adjustment. The control voltage can go up to 4, or down to 0 volts. This means that I will not need a negative voltage supply. That makes the design more simple.
