Phase Locked Frequency Controller

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- plications that require phase locked control. A precise reference fre- quency CAN be generated using the devices high frequency Oscillator and programmable Frequency Dividers The Oscillator operates using a broad range of crystals, or, CAN function as a Buffer stage to an external frequency source. 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. By Texas Instruments
