Servo input: PWM or analog

Hello all,

I am working on a "IR sensor/Schmitt Trigger" which outputs an analog signal to a Servo Motor (HS-322HD), however when plugging the servo to the Schmitt circuit it does not work

The servo seems to be wanting a PWM signal as it is going on and off in an unsteady fashion. Does this servo works with analog, if not, what would be the way to go?

The application: wave the hand at the IR sensor and have the motor turn on (a certain # of degrees) and then off.

Thanks for the help!
