Determining the Oscillator Frequency

The frequency at the oscillator is determined by the de-

sired RPM of the motor, the divide ratio selected, the

number of poles in the motor, and the state of the double

edge select pin.

OSC

(Hz) = (Divide Ratio)

(Motor RPM)

(1/60 SEC/MIN)

(No. of Rotor Poles/2)

(x 2 if Pin 5 Low)

The resulting reference frequency appearing at the phase

detector inputs is equal to the oscillator frequency divided

by the selected divide ratio. If the double edge option is

used, (Pin 5 low), the frequency of the sense amplifier in-

put signal is doubled by responding to both the rising and

falling edges of the input signal. Using this option, the loop

reference frequency can be doubled for a given motor

RPM.
