Precision Phase Locked Frequency
Control System
DESCRIPTION
The UC1633 family of integrated circuits was designed for use in phase
locked frequency control loops. While optimized for precision speed
control of DC motors, these devices are universal enough for most ap-
Crystal Oscillator
plications that require phase locked control. A precise reference fre-
Programmable Reference Frequency
quency can be generated using the device鈥檚 high frequency oscillator
Dividers
and programmable frequency dividers. The oscillator operates using a
Phase Detector with Absolute Frequency broad range of crystals, or, can function as a buffer stage to an external
frequency source.
Steering
Digital Lock Indicator
Double Edge Option on the Frequency
Feedback Sensing Amplifier
Two High Current Op-Amps
5V Reference Output
The phase detector on these integrated circuits compares the refer-
ence frequency with a frequency/phase feedback signal. In the case of
a motor, feedback is obtained at a hall output of other speed detection
device. This signal is buffered by a sense ampilfier that squares up the
signal as it goes into the digital phase detector. The phase detector re-
sponds proportionally to the phase error between the reference and the
sense amplifier output. This phase detector includes absolute fre-
quency steering to provide maximum drive signals when any frequency
error exists. This feature allows optimum start-up and lock times to be
realized.
Two op-amps are included that can be configured to provide necessary
loop filtering. The outputs of the op-amps will source or sink in excess
of 16mA, so they can provide a low impedence control signal to driving
circuits.
Additional features include a double edge option on the sense amplifier
that can be used to double the loop reference frequency for increased
loop bandwidths. A digital lock signal is provided that indicates when
there is zero frequency error, and a 5V reference output allows DC op-
erating levels to be accurately set.
