The absolute max tune voltage for the HMC586 is shown as 0 to 22 volts, with the normal operating range as 0 to 18V. Can Vtune be applied to the device before the +5 VDC? I also wanted to check if there are any concerns if the input clamp allowed a -0.3 V on the Vtune input? Could this cause an issue such as latchup when the input returns to the normal range?
Thanks and Best Regards.
