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.

(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.
